The action of acyl halides on heterocyclic compounds of five-membered rings containing an O-M-O (M = P, As, Sb) linkage is described.The reactions were either carried out in the presence of a solvent (benzene or toluene) or by direct heating of the reagent with the substrate.In the case of arsole, stibole and stannole derivatives, the cleavage of O-M bond and the formation of the respective mono- and diesters were always obtained, while with the phospholes, no cleavage of the compounds was observed.The products IIa-c (M = Sb) have been obtained in excellent yields starting from VIa-c and antimony trichloride.The structure of the compounds which were prepared was determined by analytical and spectroscopic methods and also by comparations with authentic samples where possible.
