A new and efficient method for O-glycosidation of phenols is described. Cp2HfCl2–AgClO4 is a highly effective promoter for the coupling reaction between glycosyl fluoride and phenol in the presence of molecular sieves 4A, which proceeds rapidly at low temperature to give O-aryl glycoside in high yields.
