A copper-catalzed functionalization of propiolate esters with various Grignard reagents in presence of trimethylsilyl trifluoromethanesulfonate enables the synthesis of substituted E-vinyl silanes in good yields and excellent diastereoselectivities via a catalytic carbocupration-silicon group migration sequence.
