A convenient synthesis of (E)-β-ethoxycarbonylvinylsilanes by palladium-catalysed regio- and stereo-specific hydroesterification of trimethylsilylacetylenes
Abstract
Palladium-catalysed hydroesterification of trimethylsilylacetylenes 1 gives (E)-β-ethoxycarbonylvinylsilanes 2 exclusively in excellent yields.
