摘要

New method of synthesis of six-membered heterocycles–2-R-2-oxo-4-aryl-2H-benzo [e][1, 2]- oxaphosphorin-3-enes has been developed. It includes the interaction of arylenedioxy trihalogenophosphoranes with arylacetylenes. The formation of phosphoryl group and PC bond, ipso-substitution of the aromatic oxygen and halogenation of the benzene ring take place in this unusual reaction. The influence of the phosphorane structure on synthetic ...
