Selective synthesis of E-vinylsilanes and E,E-divinylsilanes via platinum-catalyzed hydrosilylation of alkynes with secondary silanes

Abstract

Platinum-N-heterocyclic carbene complex with the formula [Pt(IPr*OMe)(dvtms)] (where IPr*OMe = 1,3-bis{2,6-bis(diphenylmethyl)-4-methoxyphenyl}imidazol-2-ylidene, dvtms = divinyltetramethyldisiloxane) exhibits a high catalytic activity towards the β-E-selective hydrosilylation of terminal acetylenes with many secondary silanes (46 examples). Depending on the ratio of the reagent concentrations, the products of mono- or disubstitution are selectively obtained. Moreover, the one-pot sequential hydrosilylation of two different alkynes with secondary silane was also achieved over the same platinum catalyst.
