Abstract

Not copy and paste: Although β-diketiminato ligands have been employed for the stabilization of GeII and SnII hydrides, the corresponding SiII hydride is not accessible. However, coordination of silicon(II) to a {Ni(CO)3} fragment allowed the isolation of the first SiII hydride metal complex 1. This complex was used for the first silicon(II)-based and Ni0-mediated, stereoselective hydrosilylation of alkynes. R=phenyl, tolyl.
