Styrene reaction with phosphorus pentachloride

The addition reaction of phosphorus pentachloride to styrene and its derivatives provides a convenient route to styrylphosphonic acids and their derivatives. " The styrene phosphorus pentachloride adduct also can be reduced with phosphorus to give the corresponding dichlorophosphine. ... 

One of the chlorine atoms in phosphorus pentachloride appears to hold a unique position in that the products of the reaction mth indene, styrene, a-methylstyrene and 5 u.-diphenylethylene m cold benzene solution, suffer hydrolysis accompanied by intramolecular separation of the fifth chlorine atom as hydrogen chloride when treated with water. At much higher temperatures certain indones add on two chlorine atoms when treated with phosphorus pentachloride, this decisively indicating the fission PCI5 PClg + Clg. 

Styrylphosphonic dichloride has been prepared by the addition of phosphorus pentachloride to styrene with subsequent reaction of the adduct with phosphorus pentoxide or sulfur dioxide. ...

The reaction is conducted in a 500-inl. three-necked flask equipped with a sealed mechanical stirrer, a dropping funnel, and a reflux condenser carrying a drying tube. The flask is flushed with dry nitrogen, and 104 g. (0.50 mole) of phosphorus pentachloride in 150 ml. of dry benzene is added. The mixture is cooled in an ice bath (Note 1) and stirred while a solution of 26 g. (0.25 mole) of styrene in 50 ml. of dry benzene is added...
