A Highly Efficient Copper-Catalyzed Synthesis of Unsymmetrical Diaryl- and Aryl Alkyl Chalcogenides from Aryl Iodides and Diorganyl Disulfides and Diselenides

An efficient and convenient protocol has been developed for the copper-catalyzed reaction of aryl iodides and diorganyl disulfides and diselenides. A variety of symmetrical and unsymmetrical diaryl- and aryl alkyl chalcogenides were synthesized with good functional group tolerance and chemoselectivity by using copper(I) iodide as a catalyst, 4?-(4-methoxyphenyl)-2,2?:6?,2??-terpyridine as ligand, and KOH as base under an inert atmosphere.

Iron-Catalyzed Regioselective alpha-C-H Alkylation of N-Methylanilines: Cross-Dehydrogenative Coupling between Unactivated C(sp3)-H and C(sp3)-H Bonds via a Radical Process

The iron-catalyzed alpha-C-H alkylation of N-methylanilines without any directing group by cross-dehydrogenative coupling between unactivated C(sp3)-H and C(sp3)-H bonds has been established for the first time, which provides a good complement to C(sp3)-H activation reactions and expands the field of Fe-catalyzed C-H functionalizations. Many different C(sp3)-H bonds in cyclic alkanes, cyclic ethers, and toluene derivatives can be used as coupling partners. Mechanistic investigations including the radical reaction process, the main role of various reagents, and the kinetic isotope effect experiment were also described.

BINOL derivatives with aggression-induced emission

As fluorescent probes, the small Stokes shift and ACQ effect limit the application of BINOL derivatives. Herein, a new series of BINOL derivatives were synthesized which could be turned from ACQ to AIE fluorophores by changing the electron withdrawing group. Among these compounds, BIN-COP exhibits an obvious AIE property with low cytotoxicity. The bioimaging performance indicated that the designed fluorophores could be successfully used for bioimaging.

Synthesis, structures and stabilities of thioanisole-functionalised phosphido-borane complexes of the alkali metals

Treatment of the secondary phosphine {(Me3Si) 2CH}PH(C6H4-2-SMe) with BH3¡¤ SMe2 gives the corresponding phosphine-borane {(Me 3Si)2CH}PH(BH3)(C6H 4-2-SMe) (9) as a colourless solid. Deprotonation of 9 with n-BuLi, PhCH2Na or PhCH2K proceeds cleanly to give the corresponding alkali metal complexes [[{(Me3Si)2CH} P(BH3)(C6H4-2-SMe)]ML]n [ML = Li(THF), n = 2 (10); ML = Na(tmeda), n = ? (11); ML = K(pmdeta), n = 2 (12)] as yellow/orange crystalline solids. X-ray crystallography reveals that the phosphido-borane ligands bind the metal centres through their sulfur and phosphorus atoms and through the hydrogen atoms of the BH3 group in each case, leading to dimeric or polymeric structures. Compounds 10-12 are stable towards both heat and ambient light; however, on heating in toluene solution in the presence of 10, traces of free phosphine-borane 9 are slowly converted to the free phosphine {(Me3Si)2CH}PH(C 6H4-2-SMe) (5) with concomitant formation of the corresponding phosphido-bis(borane) complex [{(Me3Si) 2CH}P(BH3)2(C6H4-2-SMe)] Li (14).

Complexation of Am(III) and Nd(III) by 1,10-phenanthroline-2,9-dicarboxylic acid

The complexant 1,10-phenanthroline-2,9-dicarboxylic acid (PDA) is a planar tetradentate ligand that is more preorganized for metal complexation than its unconstrained analogue ethylendiiminodiacetic acid (EDDA). Furthermore, the backbone nitrogen atoms of PDA are aromatic, hence are softer than the aliphatic amines of EDDA. It has been hypothesized that PDA will selectively bond to trivalent actinides over lanthanides. In this report, the results of spectrophotometric studies of the complexation of Nd(III) and Am(III) by PDA are reported. Because the complexes are moderately stable, it was necessary to conduct these titrations using competitive equilibrium methods, competitive cation complexing between PDA and diethylenetriaminepentaacetic acid, and competition between ligand protonation and complex formation. Stability constants and ligand protonation constants were determined at 0.1 mol¡¤L-1 ionic strength and at 0.5 mol¡¤L-1 ionic strength nitrate media at 21 ¡À 1 C. The stability constants are lower than those predicted from first principles and speciation calculations indicate that Am3+ selectivity over Nd3+ is less than that exhibited by 1,10-phenanthroline.

A novel approach to the enantioselective formal synthesis of pumiliotoxin 251D

An efficient enantioselective synthesis of the indolizidine framework 9 of pumiliotoxin 251D in good yield by using a Lewis acid (cat.)-promoted diastereoselective addition of ethyl lithiopropiolate to ketone 7 derived from L-proline as a key step is reported. Hydrogenation of the addition product 8a gave the desired lactam 9. At the same time the 8-epimer of 9 was synthesized for the first time.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 1271-19-8, you can also check out more blogs about1271-19-8
