A review of the chemistry of the reactions between trivalent phosphorous derivatives and sources of positive halogen is presented. The alkylation of various nucleophilic substrates has been achieved using alkoxy-tris(dimethylamino)phosphonium hexafluorophosphates. In particular a new method for the preparation of alkyl aryl ethers and alkyl aryl sulphides has been developed which is both stereospecific and proceeds without rearrangement. The alkoxy-tris(dimethylamino)phosphonium hexafluorophosphates are stable, highly crystalline solids,which can be stored for long periods of time with no sign of decomposition.
