ACTION OF SULFURIC ACID ON ORGANOPHOSPHORUS COMPOUNDS CONTAINING β-CHLOROSTYRYL GROUPS

By the action of concentrated sulfuric acid on bis(β-chlorostyryl)phosphonic acid and on trichlorobis(β-chlorostyryl)phosphorane with subsequent hydrolysis we obtained, depending on the reactant ratio, diphenacylphosphinic acid or products of its cyclization: 4-hydroxy-2,6-diphenyl-4H-1,4-oxaphosphorin 4-oxide and 4,4'-oxybis.By the action of concentrated sulfuric acid on (β-chlorostyryl)phosphonic acid (or dichloride) and its diesters we obtained phenacylphosphonic acid and its diesters respectively.
