A new substrate class for nickel-catalyzed C(sp3) cross-coupling reactions is reported. α-Oxy radicals generated from benzylic acetals, TMSCl, and a mild reductant can participate in chemoselective cross-coupling with aryl iodides using a 2,6-bis(N-pyrazolyl)pyridine (bpp)/Ni catalyst. The mild, base-free conditions are tolerant of a variety of functional groups on both partners, thus representing an attractive C-C bond-forming approach to dialkyl ether synthesis. Characterization of a [(bpp)NiCl] complex relevant to the proposed catalytic cycle is also described.

Nucleophilic substitution reactions of substituted benzhydryl chlorides with anilines in acetonitrile and methanol are investigated.The reactions are found to proceed by the attack of nucleophile on the preformed carbocation, I, within the ion pair.The cr

Solvolyses of monosubstituted benzhydryl bromides gave excellent linear correlations of logk with ?(1+) constants, and not with Y(BnBr) or Y(Br).Correlation analyses against corresponding logk of α-tert-butyl-(2-naphthyl)methyl bromide provided evidence for the importance of different extent of solvation in delocalized transition state and for nucleophilic solvent intervention in the solvolysis of benzhydryl systems.

Upon UV irradiation in benzene-methanol (1:2) tetraarylmethanes or 3-(triarylmethyl)pyridines underwent an α,α-elimination of two aryl groups to give biaryls or 3-arylpyridine, and two corresponding carbene intermediates.The latters afforded methyl ethers by O-H insertion to methanol.
