C1 exhibited highlyregio- and stereoselectivehydrosilylation of alkynes with primary and secondary silane to produce α-vinylsilanes. More importantly, C1 shows high regioselectivity for electronically unbiased alkyl alkynes, and the α-selectivity of some alkyl alkynes has not been achieved in previous reports. Leaching tests and reusability proved that the reaction is a heterogeneous process.
