Organic reactions that involve the direct functionalization of non-activated C-H bonds represent an attractive class of transformations which maximize atom- and step-economy, and simplify chemical synthesis. Due to the high stability of C-H bonds, these processes, however, have most often required harsh reaction conditions, which has drastically limited their use as tools for the synthesis of complex organic molecules. Following the increased understanding of mechanistic aspects of C-H activation gained over recent years, great strides have been taken to design and develop new protocols that proceed efficiently under mild conditions and duly benefit from improved functional group tolerance and selectivity. In this review, we present the current state of the art in this field and detail C-H activation transformations reported since 2011 that proceed either at or below ambient temperature, in the absence of strongly acidic or basic additives or without strong oxidants. Furthermore, by identifying and discussing the major strategies that have led to these improvements, we hope that this review will serve as a useful conceptual overview and inspire the next generation of mild C-H transformations.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1660-93-1 is helpful to your research. Computed Properties of C16H16N2

In the presence of an iridium 3,4,7,8-tetramethyl-1,10-phenanthroline catalyst, a methyl group on the silicon atom of alkyltrimethylsilanes undergoes selective C-H borylation with bis(pinacolato)diboron in cyclooctane at 135 C to give alkyl(borylmethyl)dimethylsilanes. The C-H borylation of tetramethylsilane takes place efficiently at 100 C. Permethyloligosilanes can also undergo C-H borylation without cleavage of the Si-Si bonds.

Among 18 human chemokine receptors, CCR1, CCR4, CCR5, and CCR8 were activated by metal ion Zn(II) or Cu(II) in complex with 2,2?-bipyridine or 1,10-phenanthroline with similar potencies (EC50 from 3.9 to 172 muM). Besides being agonists, they acted as selective allosteric enhancers of CCL3. These actions were dependent on a conserved glutamic acid at TM-7 (VII:06/7.39). A screening of 20 chelator analogues in complex with Zn(II) identified compounds with increased potencies, with 7 reaching highest potency at CCR1 (EC50 of 0.85 muM), 20 at CCR8 (0.39 muM), and 8 at CCR5 (1.0 muM). Altered selectivity for CCR1 and CCR8 over CCR5 (11, 12) and a receptor-dependent separation of allosteric from intrinsic properties were achieved (20). The pocket similarities of CCR1 and CCR8, contrary to CCR5 as proposed by the ligand screen, were elaborated by computational modeling. These studies facilitate exploration of chemokine receptors as possible targets for therapeutic intervention.

Physicochemical properties constitute a key factor for the success of a drug candidate. Whereas many strategies to improve the physicochemical properties of small heterocycle-type leads exist, complex hydrocarbon skeletons are more challenging to derivatize because of the absence of functional groups. A variety of C-H oxidation methods have been explored on the betulin skeleton to improve the solubility of this very bioactive, yet poorly water-soluble, natural product. Capitalizing on the innate reactivity of the molecule, as well as the few molecular handles present on the core, allowed oxidations at different positions across the pentacyclic structure. Enzymatic oxidations afforded several orthogonal oxidations to chemical methods. Solubility measurements showed an enhancement for many of the synthesized compounds.

Near infrared-emitting tris-bidentate Os(ii) phosphors: Control of excited state characteristics and fabrication of OLEDs

A series of four Os(ii) complexes bearing (i) chromophoric diimine ligands (N^N), such as 2,2?-bipyridine (bpy) and substituted 1,10-phenanthrolines, (ii) dianionic bipz chelate ligands derived from 5,5?-di(trifluoromethyl)-2H,2?H-3,3?-bipyrazole (bipzH2), and (iii) bis(phospholano)benzene (pp2b) as the third ancillary ligand completing the coordination sphere were synthesized. X-ray diffraction studies confirm the heteroleptic tris-bidentate coordination mode. These Os(ii) complexes [Os(N^N)(bipz)(pp2b)], N^N = bpy (3), phenanthroline (4), 3,4,7,8-tetramethyl-1,10-phenanthroline (5) and 4,7-diphenyl-1,10-phenanthroline (6), display near infrared (NIR) emission between 717 nm and 779 nm in the solid state at RT. On the basis of hybrid-DFT and TD-DFT calculations, the emissions are assigned to metal-to-ligand charge transfer transitions (3MLCT) admixed with small ligand-to-ligand charge transfer (3LLCT) contributions. Successful fabrication of organic light emitting diodes (OLEDs) using Os(ii) complex 5 as the dopant and either tris(8-hydroxyquinoline) aluminum (Alq3) or 3,3?,5,5?-tetra[(m-pyridyl)-phen-3-yl]-biphenyl (BP4mPy) as the host is reported. These OLEDs were measured with emission maxima at 690 nm and extending into the NIR, with peak power efficiencies of up to 0.13 lm W-1 and external quantum efficiencies of up to 2.27%.

Two mononuclear single molecule magnets derived from dysprosium(iii) and tmphen (tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline)

Two mononuclear Dy(iii) complexes, [DyIII(hfac)3(tmphen)] (1) and [DyIII(acac)3(tmphen)]·2H2O (2) (tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline, hfac = hexafluoroacetylacetone, acac = acetylacetone) have been synthesized and structurally characterized by single crystal X-ray diffraction. Magnetic properties indicate that both of the complexes exhibit SMM behavior, and complex 1 is the first typical derivative of phenanthroline containing D2d-Dy(iii) based mononuclear single molecule magnets. The energy barrier (Ueff/kB) of complex 2 (130.42 K) is much higher than that of complex 1 (35.09 K), indicating that the local symmetry of Dy(iii) ions (D2d for 1, D4d for 2) plays an important role in magnetic behaviors.

Deaminative Strategy for the Visible-Light-Mediated Generation of Alkyl Radicals

A deaminative strategy for the visible-light-mediated generation of alkyl radicals from redox-activated primary amine precursors is described. Abundant and inexpensive primary amine feedstocks, including amino acids, were converted in a single step into redox-active pyridinium salts and subsequently into alkyl radicals by reaction with an excited-state photocatalyst. The broad synthetic potential of this protocol was demonstrated by the alkylation of a number of heteroarenes under mild conditions.

Lanthanide-3d cyanometalate chains Ln(III)-M(III) (Ln = Pr, Nd, Sm, Eu, Gd, Tb; M = Fe) with the tridentate ligand 2,4,6-tri(2-pyridyl)-1,3,5-triazine (tptz): Evidence of ferromagnetic interactions for the Sm(III)-M(III) compounds (M = Fe, Cr)

A series of cyanide-bridged chain mixed Fe(iii)/Ln(iii) (Ln = Pr, Nd, Sm, Eu, Gd, Tb) complexes with the tridentate ligand 2,4,6-tri(2-pyridyl)-1,3,5- triazine (tptz) used as a capping group has been prepared. Reactions of tptz and LnCl3 with K3Fe(CN)6 yield a family of air-stable 1-D compounds {[Pr(tptz)(H2O)4Fe(CN) 6]·8H2O}? (1), {[Nd(tptz)(H 2O)4Fe(CN)6]·8H2O} ? (2), {[Sm(tptz)(H2O)4Fe(CN) 6]·8H2O}?

Temperature dependent magnetic susceptibility studies of 1-6 reveal that in 3, the Sm(iii) and Fe(iii) ions are ferromagnetically coupled with 3-D ordering occurring below 3.5 K. The appearance of the frequency dependent out-of-phase signal is explained in terms of an ordering with a spin glass-like behavior.
