Abstract

Abstract Die Darstellung verschiedener Triphenylphosphin-acyl-carbomethoxy-methylene aus Triphenylphosphin-carbomethoxy-methylen mit Carbonsäure-chloriden wird beschrieben. Dieselben zerfallen bei 220–250 unter Bildung von entsprechend substituierten α. β-Acetylencarbonsäuren und Triphenyl-phosphinoxyd.
