Nickel-catalyzed regiodivergent syn-hydrosilylation of disubstituted alkynes

Modular access to alkenylsilanes was reported via nickel-catalyzed regiodivergent and stereoselective hydrosilylation of disubstituted alkynes. Herein, strategic use of an amide backbone and the appropriate selection of ligands allows highly regiocontrol and stereocontrol in the key syn -silametallation step.
