Phosphorylation of diols using sterically bulky cyclic phosphoramidites was performed in a good selectivity. Their phosphite derivatives underwent tetrazole-catalyzed hydrolysis and transesterification. The reaction was shown to proceed via a phosphorane intermediate by NMR analysis.

1H-Tetrazole-catalysed transesterification of a trialkyl phosphite with an alcohol and a (31)P NMR experiment in the case of 4,4,5,5-tetramethyl-2-(3-phenylpropoxy)-1,3,2-dioxaphospholane showed the existence of the corresponding cyclic five-coordinate hydrophosphorane as an intermediate.
