The phosphoryl transfer reactions of diphenyl chlorophosphate with a wide range of alcohols were catalyzed by tris(pentafluorophenyl)boron [B(C 6F5)3], giving the corresponding phosphate esters in excellent yields. This me

(Chemical Equation Presented) Phosphoryl transfer from N-phosphoryl 5,5-diphenyl oxazolidinone is efficiently catalyzed by copper(II) triflate. The utility of this method has been demonstrated in the phosphorylation of representative primary, secondary, tertiary, phenolic, and allylic alcohols. These reaction conditions are significantly milder than employing alkoxides and allow the phosphorylation of biologically relevant molecules.

Several inorganic esters have been evaluated as phosphoryl transfer catalysts. Of these, Ti(t-BuO)4 was found to be the most effective catalyst giving excellent yields of the desired phosphate esters. The loading of the catalyst could be reduced to a little as 5 mol % for a majority of substrates with no loss in the yield of product. This methodology is significantly more versatile than using TiCl4 and is suitable for the phosphorylation of more complex carbohydrates and molecules of biological interest.
