The reactions of trichloro(2-ethoxyethenyl)phosphonium and trichloro(styryl)phosphonium hexachlorophosphorates with triethylamine were studied by 1H, 13C, and 31P NMR spectroscopy. It was shown that phosphonyl chlorides are the primary products of the reactions. The presence of the alkoxy group in hexachlorophosphorate results in the oxidation of the PCl2 group to form phosphonyl chlorides. Diphosphorylated oxaphosphinines were synthesized.
