Palladium - catalyzed reactions of trialkylstannyl phenyl sulfides with alkenyl bromides. A new diastereoselective synthesis of (E)-1-alkenyl phenyl sulfides

Abstract The reaction of easily available stereoisomeric mixtures of 1-alkenyl bromides with molar excesses of trialkylstannyl phenyl sulfides takes place readily in the presence of Pd(PPH 3 ) 4 to afford diastereoselectively (E)-1-alkenyl phenyl sulfides in excellent yields.
