In addition to phosphonyl dichlorides, a significant amount of phosphoryl dichlorides was obtained by the reaction of propyl and allyl halides with phosphorus trichloride in oxygen atmosphere. Formation of the P–O–C bond can be explained by a scheme involving a preferential reaction of the bridged intermediate radical with oxygen.
