A facile method for stereoselective synthesis of (E)-styryl bromides by the reduction of 1,1-dibromoalkenes using LiAlH4-EtOAc (1:1) is described. We believe that the present procedure is a good alternative to the Tokuda's microwave method with good stereoselectivity.

trans-β-Bromostyrenes have been conveniently prepared in moderate to high yield in a one-pot two-step sequence. trans-1,2-Bis(tri-n-butylstannyl)ethylene underwent a smooth palladium(0) catalyzed coupling reaction with 0.5 equivalents of aromatic bromide or iodide to furnish a trans-β-stannylstyrene.This intermediate vinyl stannane, without isolation, was then converted to the substituted trans-bromostyrene on treatment with molecular bromine.
