摘要:
The products of reaction of o-phenylenedioxytrichlorophosphorane with arylacetylenes were identified as 4-aryl-2-chloro-2-oxo-5,6-(4-chlorobenzo)phosphorin-3-enes using H-1, C-13, P-31 NMR, and IR spectroscopy and high-resolution mass spectrometry.

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 P-C bond, ipso-substitution of the aromatic oxygen and halogenation of the benzene ring take place in this unusual reaction. The influence of the
