Abstract

Abstract Reaction in a three-component system tetrachloro-o-benzoquinone-arylacetylene- phosphorus trichloride was investigated with the use of NMR and IR spectroscopy and high resolution mass spectrometry. It was established that prevailingly formed 4-aryl-2-oxo-2, 5, 6, 7, 8-pentachlorobenzo [e]-1, 2-oxaphosphorin-3-enes which on hydrolysis furnished 2- aryl-2-(1-hydroxy-2, 3, 4, 5-tetrachlorophenyl) vinylphosphonic acids.
