Abstract

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 ...
