The lithium complexes [Li{N(Ar)C(H)N(Ar)}(pmdeta)], where Ar = 2,6-R 2C6H3 (R = Me (1), Et (2) and iPr (3)) and pmdeta = N,N,N?N?,N?-pentamethyldiethylenetriamine, have been synthesised and their solid state structures determined by X-ray methods. Compounds 1-3 comprise a Li(pmdeta) centre coordinated by a bulky formamidinate in either the E-syn or E-anti isomeric form. The structures of compound 3 and one unique molecular unit of compound 1 (E-anti isomer) display coordination of the pendant amidinate imine, and can therefore be considered the first examples of eta2:eta1-C=N,N? metal amidinate coordination.

A range of solid supported pyridinemethanimine 9-11 and polyamine 12-15 ligands have been prepared on silica, polystyrene, and JandaJel supports. The CuCl and CuBr complexes of these supported ligands have been used to assess both the effect of the ligand type and the nature of the support upon a representative range of copper-mediated atom transfer 5-exo-trig 6, 24-25, 5-exo-dig 26, 4-exo-trig 28, and 5-endo-trig 27, 38 radical cyclizations to give nitrogen heterocycles. In addition, the effect of the nature of the support on the stereochemical outcome of the 5-exo cyclization of 25 has been probed. Generally, it was found that the type of support (e.g., polystyrene, silica, or JandaJel) had very little effect upon the efficiency and selectivity of the processes but that the nature of the ligand type immobilized was the important factor. Thus, the 5-exo cyclization of 6 and 24-26 proceeded more rapidly with the PMI ligands 9-11, whereas 4-exo cyclizations 28 and 5-endo radical polar crossover reactions 27 and 38 proceeded more efficiently with the JJ-TEDETA ligand 15. The efficiency of the supported ligands was also compared to their solution counterparts 4 and 5. The reusability of P-PMDETA ligand system 13 was assessed in the cyclization of 6.

Abstract: Here triblock copolymer synthesis mediated by trans-1,4-polyisoprene is reported for the first time. Carbonyl telechelic trans-1,4-polyisoprene (trans-structure >95%) was synthesized by the epoxidation of trans-1,4-polyisoprene followed by oxidative cleavage. Bromine terminated trans-1,4-polyisoprene was then synthesized by the reduction reaction of carbonyl groups of trans-1,4-polyisoprene to hydroxyl groups followed by end group transformation. Atom transfer radical polymerization of styrene was conducted then using bromine terminated trans-1,4-polyisoprene as macroinitiator. Triblock copolymers were characterized by 1H-NMR, FTIR, GPC, DSC, and XRD.

The synthesis of a range of 1,2-diphospholides can be achieved by a one-pot procedure involving the reactions of aromatic primary phosphines bearing ortho-CH2 substituents with the superbase mixture of nBuLi/Sb(NMe2)3 in the presence of the Lewis base donor TMEDA (Me2NCH2CH2NMe2). The synthesis of the parent benzo-1,2-diphospholide and the substituted derivatives 4-methoxybenzo-1,2-diphospholide, 9-methylbenzo-1,2-diphospholide, and naphtho-1,2-diphospholide are reported from readily prepared primary phosphines. Bulk synthesis of the potassium salt of the previously reported 4,6-dimethylbenzo-1,2-diphospholide anion using this route provides a convenient starting material for reactivity studies.

A well-defined (BA)(AC)2 miktoarm star diblock copolymer, (PPEGMA32-b-PMMA41)-b-(PMMA45-b-PNIPAm19)2, is synthesized by the combination of ATRP and click reaction. The miktoarm star block copolymer and its precursors are characterized by means of NMR and SEC/MALLS measurements. The copolymer exhibits a low critical aggregation concentration in aqueous solution. Micelles that self-assemble from the copolymer are prepared in aqueous solution below 15 C by a sonication method. The micelles have a PMMA core and a PPEGMA/PNIPAm corona and exhibit temperature sensitivity. Using celecoxib as a guest molecule, it is found that the loading capacity of the star copolymer is 8.8 wt% and the celecoxib release from the loaded self-assembly is temperature tunable.

Metal-free atom transfer radical polymerization (ATRP) was successfully achieved in aqueous media for the first time. Polymerization of poly(ethylene oxide) methyl ether acrylate (PEGA480) was well controlled (Crossed D sign < 1.40) under visible light irradiation using tetrabromofluorescein (Eosin Y) as catalyst and pentamethyldiethylenetriamine (PMDETA) as electron donor. A validated kinetic model was developed to investigate the process of photoredox catalytic cycle via reductive quenching pathway. Experimental and simulation results showed that electron donor not only had an important influence on the ATRP activation, but also participated in the ATRP deactivation. Furthermore, the effects of water content, catalyst concentration, and degree of polymerization on the polymerization were studied thoroughly by a series of experiments. Good controllability of the polymerization regulated by light on and off confirmed the high degree of temporal control. The livingness of the chains was proved by a successful chain extension experiment. Both experimental and simulation techniques were used to study aqueous metal-free ATRP, which provided a promising method to synthesize polymers in the absence of metal and organic solvent.

The MF3·3H2O (M = Al, Ga or In) dissolve in hot dimethylsulfoxide (dmso) to form [MF3(OH2)2(dmso)]; further dmso is not incorporated even after prolonged reflux. The X-ray structure of [GaF3(OH2)2(dmso)] shows mer fluorides and trans OH2 ligands. The [GaF3(OH2)2(dmso)] reacts with Me3tacn (1,4,7-trimethyl-1,4,7-triazacyclononane) or 2,2?-bipyridyl to give good yields of [GaF3(Me3tacn)]·xH2O and [GaF3(bipy)(OH2)]·2H2O at room temperature, previously obtained from GaF3·3H2O by a hydrothermal route. [MF3(OH2)2(dmso)] (M = Al or Ga) do not react with R3PO (R = Me or Ph) in CH2Cl2 or MeOH, but with pyNO (pyridine-N-oxide), the products were [AlF3(OH2)2(pyNO)] and [GaF3(OH2)2(pyNO)]·pyNO·H2O. The structure of the latter shows equal numbers of the geometric isomers with mer-trans and mer-cis geometries, as well as lattice pyNO and H2O. Pentamethyldiethylenetriamine (PMDTA) and [GaF3(OH2)2(dmso)] react to produce the zwitterion [GaF4(PMDTAH)]·2H2O, which contains kappa2-PMDTA with the ‘free’ NMe2 group protonated to balance the charge of the GaF4- unit. Crystals of [?Me2N(CH2)2NMe(CH2)2]2[Ga2F8(OH2)2]·H2O containing a 1,1,4-trimethylpiperazinium cation, were obtained as a minor by-product. The anion is an edge-shared fluoride-bridged dimer, with the coordinated water ligands arranged anti. Attempts to prepare complexes with phosphine or thioether ligands by Cl/F exchange from the corresponding chloro-complexes with [NMe4]F were unsuccessful, halide exchange being accompanied by liberation of the soft donor ligand. X-ray structures are also reported for [Me2NH2][trans-GaF4(OH2)2] and [AlCl3(OAsPh3)].

The structures of the lithium salts of the chiral bicyclic allylic alpha-sulfonyl carbanions 3-5, each possessing a norbornane skeleton and a tert-butyl group at the S atom, have been studied by 1H, 13C, 6Li, and 6Li,1H HOESY NMR spectroscopy, cryoscopy, and X-ray crystal structure analysis. Because of their relatively high endo-exo isomerization barriers, the Calpha-S endo and exo diastereomers of 3-5 could be observed by NMR spectroscopy at -30 C to -50 C in [D8]THF. The endo diastereomer is the preferred equilibrium species under these conditions, as shown by 1H,1H HOESY experiments. Carbanion salt 3 has endo-exo isomerization barriers of DeltaG270# = 13.1±0.1 kcal/mol and 12.6±0.1 kcal/mol, while the 7-benzhydrylidene-substituted carbanion salt 5 has barriers of DeltaG288# = 13.5±0.1 kcal/mol and 13.3±0.1 kcal/mol. Cryoscopy and 6Li NMR spectroscopy of 5 in THF at -100 C to -108 C revealed the formation of dimers and monomers in a ratio of approximately 2:1. NMR spectroscopy of 3-5 at -90 C to -105 C allowed observation of the dimers and monomers of which the anions have endo conformations and also of which the anions adopt exo conformations. The NMR spectroscopic results for 3-5 are compatible with monomeric and dimeric CIPs, featuring planar allylic moieties and allylic stabilization by delocalization of the negative charge. 6Li,1H HOESY examination of the mixture of the monomers and dimers of endo-5 and exo-5 in [D8]THF at room temperature gave only evidence for coordination of the Li atom to the O atom(s) in the CIPs. The NMR spectroscopic results for 3 were corroborated by X-ray crystal structure analysis of the monomer exo-3·PMDETA, which features (i) an essentially planar anionic C(2) atom, (ii) the exo conformation, (iii) the typical Calpha-S conformation, also allowing for a stabilizing nC-sigma StBu interaction, and (iv) a single O-Li bond, but no C-Li bond. Upon treatment of the endo and exo sulfones 9, 10, and 12 with nBuLi at very low temperatures, the corresponding endo and exo carbanion salts endo-3-5 and exo-3-5, respectively, were selectively generated as mixtures of monomers and dimers, the reactions of which with electrophiles were studied. Deprotonation of the exo and endo sulfones with nBuLi proceeds stereoselectively, the exo sulfone preferentially giving the endo anion and vice versa. The diastereomeric endo and exo carbanion salts 3-5 each react with reactive electrophiles at the anionic C(2) atom syn to the sulfonyl O atoms, giving the corresponding substituted endo and exo sulfones, respectively, with significant degrees of asymmetric induction. Reactions of the endo and exo diastereomers of 3-5 with CF3COOD and MeOCH2I were faster than their endo-exo isomerization and approached kinetic quenching, while those with MeI and allyl iodide were slower, approaching the Curtin-Hammett limit and preferentially giving the exo sulfones. Deprotonation-deuteration experiments of the 7-oxa-sulfone endo-11 showed that the corresponding 7-oxa-substituted carbanion salts endo-6 and exo-6 not only can be generated at low temperatures but may also, despite their tendency to rearrange, be converted into the corresponding 7-oxa-sulfones on treatment with reactive electrophiles.

Selective cleavage of a silicon?carbon bond in tetraorganosilanes is still a great challenge. A new type of Si?C(sp3) bond cleavage in bench-stable (aminomethyl)silanes with common organolithium reagents as nucleophiles has now been identified. Suitable leaving groups are benzyl, allyl, and phenylthiomethyl groups. A beta-donor function and polar solvents are essential for the reaction. Simple switching between alpha-deprotonation and substitution is possible through slight modifications of the reaction conditions. The stereochemical course of the reaction was elucidated by using a silicon-chiral benzylsilane. The new transformation proceeds stereospecifically with inversion of configuration and can be used for the targeted synthesis of enantiomerically pure tetraorganosilanes, which are otherwise difficult to access. Quantum chemical calculations provided insight into the mechanism of the new substitution.
