N-Trimethylsilylvaline trimethylsilyl ester Ⅱa,N-triethylsilylvaline triethylsilyl ester Ⅱb and N-tert-butyldimethylsilylvaline tert-butyldimethylester Ⅱc showed evidently different reactivities with O,O'-phenylenephosphorylchloride.The formation speed of the final spiro-bicyclic pentacoordinated phosphorus compounds Ⅳ depends on the intramolecular transfer ability of the silyl oiety crucially.
