Abstract

Benzaldehydes undergo Wittig olefination with alkoxycarbonylmethylidenephosphorane in 10w% aqueous NaOH. The cinnamates are hydrolysed under the conditions and cinnamic acids are obtained after simple extractive work-up. Under the same conditions, benzaldehydes react with alkoxycarbonylbromomethylidenephosphorane to give arylpropiolic acids.
