  A new convenient synthetic protocol for the one-pot ste- reoselective synthesis of bis((E)-4-bromo(or chloro)styryl)arene derivatives via the sequential reaction of silylative-coupling of 4- halostyrenes with vinylsilanes followed by palladium-catalyzed cross-coupling 4-halostyrylsilanes with diiodoarenes, is described. The reaction leads to symmetrical bis((E)-4-halostyryl)arene deriv- atives obtained
