Aryl–aryl interactions as directing motifs in the stereodivergent iron-catalyzed hydrosilylation of internal alkynes

Abstract

The defined Fe hydride complex FeH(CO)(NO)(Ph(3)P)(2) is highly active as a catalyst for selective hydrosilylation of internal alkynes to vinylsilanes. Depending on the silane employed either E- or Z-selective hydrosilylation products were formed in excellent yields and good to excellent stereoselectivities.
