Abstract
Abstract Potassium hydroxide and a catalytic amound of 18-crown-6 are used, in alternative to the classical Wittig conditions, to prepare very rapidly and stereoselectively Z- and E-stilbenes. In particular, the use of benzyltriphenylphosphonium iodides always leads to a complete Z- stereospecificity, while benzyldiphenylchlorophosphonium salts give a complete E-stereospecificity.
