Mecanisme de formation et de transformation des spirophosphoranes—VIII: Reactions des spirophosphoranes a liaison PH avec les reactifs electrophiles

The reactions of spirophosphoranes containing a PH bond with aldehydes, imines, and animals lead to spirophosphoranes (10–10) containing a PC bond, while with acid chlorides, β-functional phosphiates are formed (compounds 35–38). Dependeing on the nature of the heteroatom attached to phosphorus, the reaction of spirophosphoranes with phenyl isocyanate gives a spirophosphorane (YHOH, compounds 31 and 32) or a phosphite (YHNHR, compounds 33 and 34).
