A process for the preparation of the formulawherein Ar1 and Ar2 are individually aromatic of 6 to 20 carbon atoms or heteroaromatic of 4 to 9 carbon atoms, each unsubstituted or substituted with at least one member of the group consisting of halogen, carboxyl, -OH, alkyl of 1 to 6 carbon atoms, phenyl and naphthyl, Ar1 has one valence and R2 has y+1 valences, x is an integer of 1, 2 or 3, y is 1 or 2, Z is carbohydrate with a glycosidic bond comprising reacting a hydrocarbon halide of the formulain a multi-phase reaction medium in the presence of a base and a phase transfer catalyst to form a phosphane of the formulaand removal of the protective groups to form a compound of Formula I, metal complexes thereof and various processes.
