General description

N-(Phenylthio)phthalimide is an N-substituted phthalimide. It is used as a sulphenylating agent. The synthesis of N-(phenylthio)phthalimide has been reported.

Application

N-(Phenylthio)phthalimide is suitable reagent used in the synthesis of phenyl (3-trimethoxysilylpropyl)-disulfide. It may be used in the sulfenylation of ylides and β−keto esters.
N-(Phenylthio)phthalimide may be used as sulfenylating agent in the synthesis of the following:
  • α-phenylthio-ketones and α-phenylthio-aldehydes from aldehydes and ketones
  • 3-sulfenyl indoles from indoles
  • optically active 3-phenylthiooxindoles from unprotected 3-substituted oxindoles
  • N−alkyl-β-phenylsulfenyl-2-acetylbenzimidazole from N−alkyl−2−acetylbenzimidazole
  • N−phenylsulfenyl ketimines from oximes or nitro compounds

As N-sulfenyl imines (e.g., RR'C=N-SAr) can be readily transformed to their N-sulfinyl imines (RR'C=N-SOAr), N-sulfonyl imines (RR'C=N-SO2Ar), and N-sulfonyl oxaziridines, the very mild procedure developed to convert ketoximes and secondary nitro derivatives to N-arenesulfenyl ketimines constitutes a new and efficient
