Abstract

Based on the different reactivity of stannyl and bromo groups, (Z)-α-bromovinylstannanes can undergo the cross-coupling reaction with alkynyl Grignard reagents in the presence of tetrakis(triphenylphosphine)palladium(O) catalyst in THF at room temperature to afford stereoselectively 1,3-enynylstannanes in good yields.
