The new data concerning the reaction between substituted arylenedioxy trihalogenophosphoranes and monoalkyl- or arylacetylenes are summarized. The reaction leads to formation of six-membered heterocycles-2-oxo-4-R-benzo[e]-1,2-oxaphosphorin-3- enes. The substituent effects in the phosphorane and acetylene molecules on the ipso-substitution and halogenation regiochemistry are discussed. The ipso-substitution of tert-butyl group on chlorine and the exchange of bromine on chlorine and iodine on hydrogen have been observed, along with formation of benzophosphorines. The interaction of tetrachloro-ortho-benzoquinone with phosphorus trichloride and arylacetylenes is proposed as a new modification of the reaction leading to the formation of benzo[e]-1,2-oxaphosphorines. The structures of some benzo[e]-1,2-oxaphosphorines are determined by the single crystal X-ray diffraction.
