Abstract
1H-Tetrazole-catalysed transesterification of a trialkyl phosphite with an alcohol and a 31P 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.Keywords
