## Abstract Stereospecific synthesis of a family of novel (__E__)‐2‐aryl‐1‐silylalka‐1,4‐dienes or (__E__)‐4‐aryl‐5‐silylpenta‐1,2,4‐trienes via a cross‐coupling of (__Z__)‐silyl(stannyl)ethenes with allyl halides or propargyl bromide is described. In the reaction with allyl bromide, either a Pd(db
