The vicinal functionalization of propiolate esters via a catalytic carbocupration−silicon group migration sequence has been investigated. We have observed that catalyst loadings as low as 5 mol % allow for good yields and excellent diastereoselectivities (>20:1) with a series of Grignard reagents for the synthesis of substituted E-vinyl silanes.
