One-carbon homologation has been achieved in novel syntheses of the title compounds by one-pot reaction of 1-(triphenylphosphoroylideneaminomethyl)benzotriazole (1) with Grignard reagents followed by in situ transformations of the phosphazene functionality with isocyanates, aldehydes, carbon disulfide, ethylene oxide, and alkyl halides, respectively.
