The reactions of phosphorus pentachloride with various C-, N-, O-, and S-nucleophiles are widely used for the synthesis of compounds containing one or more phosphorus-carbon bonds [1]. A feature of this method is its proceeding in two stages: the first is the formation of organyltrichlorophosphonium hexachlorophosphates Ia–Ie, and the second is the formation of the stable phosphorus chlorides III and IV at the treatment of the hexachlorophosphates ...
