Abstract :

4-Chloro-3,5-dioxaphosphacyclohepta[2,1-;3,4-']dinaphthalene (BINOL-PCl) was found to be an efficient, bulky and selective reagent for the transformation of symmetric and asymmetric benzoins to the corresponding benziles at 0 °C to room temperature under nitrogen atmosphere in good yield.
