Abstract
Abstract Vinylsilanes are highly appealing and convenient chemical derivatives, as evidenced by the increasing number of synthetic transformations utilizing this class of compounds. Herein, a new comprehensive cobalt-catalyzed procedure has been developed enabling selective hydrosilylation of internal aryl-, alkyl-, and silylalkynes. Cobalt complexes bearing triazine-based PNP pincer-type ligands provide exclusive syn-addition of primary as well as secondary silanes to C≡C bonds. As a result, (E)-silylalkenes and vicinal disilylalkenes were effectively obtained with excellent stereoselectivity and regioselectivity. Unlike several TM-catalyzed procedures, no external additives were required since hydrosilanes act as both substrates and activators.
