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.

Keywords: Cinnamic acids, arylpropiolic acids, Wittig olefination, aqueous reaction medium, dehydrobromination, hydrolysis
