Abstract

Abstract : The readily available cyclobutadiene platinum complex [(C4 Et4 )PtCl2 ] 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 (Et3 SiH, (EtO)3 SiH, Ph3 SiH) and the disubstituted silane Ph2 SiH2 . The hydrosilylation proceeds with typical anti‐Markovnikov regioselectivity giving mainly β(E)‐vinylsilanes from alkynes and linear alkyl silanes from alkenes. Abstract : Catalyst of a new type: Simple cyclobutadiene platinum complex actively catalyzes hydrosilylation of the unsaturated substrates. Due to the easy synthesis, air stability, and solubility in nonpolar media, this complex can be considered as a more convenient source of platinum than the Karstedt's catalyst.
