Highly Chemo-, Regio-, and Stereoselective Cobalt-Catalyzed Markovnikov Hydrosilylation of Alkynes
Guo, Jun,Lu, Zhan
, p. 10835 - 10838 (2016)
A highly chemo-, regio- and stereoselective cobalt-catalyzed Markovnikov hydrosilylation of alkynes was developed. Various functionalized groups, such as halides, free alcohols, free aniline, ketones, esters, amides, and nitriles are tolerated, which may lead to further applications and late-stage derivatizations. To date, this is the most efficient cobalt catalytic system (TOF=65 520 h?1; TOF=turnover frequency) for hydrosilylation of alkynes. The Hiyama–Denmark cross-coupling reactions of vinylsilanes with aryl iodides underwent smoothly to afford 1,1-diarylethenes. A unique regioselectivity-controllable hydrosilylation/hydroboration reaction of alkynes was also described.

A direct, efficient, and practical protocol to install a chiral oxazoline unit onto aryl/heteroaryl rings via palladium-catalyzed C-H functionalization of 2-positions of oxazolines with a variety of halides using dppe as the ligand has been developed. Var
Kinetic resolution by copper-catalyzed azide-alkyne cycloaddition

The use of chiral pybox ligands imparts enantioselectivity to the Cu I-catalyzed azide-alkyne cycloaddition reaction, in the form of kinetic resolution of α-chiral azides and desymmetrization of gem-diazides. While levels of selectivity are modest, the results show unequivocally that the process benefits from ligand-accelerated catalysis.
