Abstract
AbstractBased 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.
