## Abstract An efficient and highly stereoselective synthesis of densely substituted 1,3‐dienes has been achieved which entails a sequential double olefination of 2‐(arylmethylidene)‐2‐phosphonoacetonitriles by a one‐pot domino process involving Michael addition of dimsyllithium to 2‐(arylmethylide
