Phosphorus pentachloride thermal decomposition

The reactions of phosphorus pentachloride (81) with olelins continue to be studied, notably by Russian groups. These reactions generally result in formation of a complex, the nature of which is not always clear, followed by decomposition of the complex either thermally or by the action of a chemical such as sulphur dioxide. For example, the vinyl ether (94) reacts with (81) in... 

The decomposition of urethanes either thermally or in the presence of phosphorus pentachloride has been reported. An interesting new reaction involves the decomposition of phosphoramidate anions.
