Abstract
According to the NMR, IR, and high-resolution mass spectra, the major products of the reactions of 5,6-dibromo-2-chlorobenzo[d]-1,3,2-dioxaphosphole 2,2-dichloride with arylacetylenes are 4-aryl-6,7-dibromo-2-chloro-5,6-benzo[e]-1,2-oxaphosphorin-3-ene 2-oxides. The steric structure of one of the hydrolysis products, 2-hydroxy-6,7-dibromo-4-phenyl-5,6-benzo[e]-1,2-oxaphosphorin-3-ene 2-oxide, was studied by single crystal X-ray diffraction.
