Peracetates of β-glycosyl dibenzylphosphates are formed efficiently in the reaction of cesium dibenzylphosphate with peracetyl-α-glycosyl nitrates derived froml-fucopyranose,d-galactopyranose, and 2-azido-2-deoxy-d-galactopyranose or with tri-O-acetyl-α-l-fucopyranosyl bromide. On the contrary, the reaction of the above-mentioned glycosyl nitrates with cesium diphenyl phosphate leads to thermodynamically
