Abstract The reaction of 2, 2′-(tert-butylimino) diethanol (1) with dioxaphospholanes (2a) and (2b) leads to the formation of (tert-butylimino) diethylene cyclic ethylene bisphosphite (4). Thermal reaction of the biphosphite (4) with (1) gives a complete rearrangement yielding a mixture of spirophosphorane (7),(tert-butylimino) diethylene cyclic bis [(tert-butylimino) diethylene] bis (phosphite)(9) and traces of another product. The biphosphite (4) reacts ...
