Phosphorylation of 1,4:3,6-dianhydro-D-mannitol with diphenylphosphinous chloride provided a bisphosphinite derivative that, unlike what is observed in the phosphorylation with phosphorous chlorides and amides, undergoes fast phosphinite-phosphine oxide isomerization. The monophosphinite derivative, in addition, is strongly dephosphorylated. The effect of the solvents and amines (HCl acceptors) on the phosphinite-phosphine oxide isomerization is studied.
