Abstract
The readily available cyclobutadiene platinum complex [(C 4 Et 4 )PtCl 2 ] catalyzes hydrosilylation of alkenes and alkynes. The reaction typically proceeds at room temperature and does not require any solvent. The target products are obtained from both terminal and internal alkynes, as well as from terminal alkenes in 43–99% yields. The scope of silanes includes various tertiary silanes (Et 3 SiH, (EtO) 3 SiH, Ph 3 SiH) and the disubstituted silane Ph 2 SiH 2 . The hydrosilylation proceeds with typical anti‐Markovnikov regioselectivity giving mainly β(E)‐vinylsilanes from alkynes and linear alkyl silanes from alkenes.
