Preservation of the Coordination State of the Phosphorus Atoms in Tetraalkyl Pyrophosphites in Their Reaction with Tetraethylammonium Tetrafluoroborate

Tetraalkyl pyrophosphites under mild conditions (in a polar aprotic solvent at 25-50°C or heating to 200°C without solvent) react with tetraethylammonium tetrafluoroborate to give an equimolar mixture of dialkyl phosphorofluoridite and dialkyl ethyl phosphite, i.e., both the pyrophosphite phosphorus atoms preserve their coordination number 3. A mechanism of the reaction is proposed.
