Abstract

Low catalyst loadings of (IPr)Pt(allyl ether) display enhanced activity and regioselectivity for the hydrosilylation of terminal and internal alkynes. Reactions lead to exquisite regioselectivity in favor of the cis-addition product on the less hindered terminus of terminal and internal alkynes.
