Effect of Silyl Moiety on the Reaction of O,O'-Phenylenephosphoryl Chloride with N-Silylvaline Silyl Ester
Effect of Silyl Moiety on the Reaction of O,O'-Phenylenephosphoryl Chloride with N-Silylvaline Silyl Ester
摘要
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 fmal spiro-bicyclic pentacoordinated phosphorus compounds IV depends on the intramolecular transfer ability of the silyl moiety crucially
