weakly nucleophilic nitrogen derivatives including carbamates, amides, sulfonamides, and anilines were reacted with 1,2‐bis(trimethylsilyloxy)cyclobutene under acidic conditions to afford various substituted 2‐aminocyclobutanone derivatives 3a–i in modest to excellent yields.

The deoxyfluorination of α-N-phthaloyl cyclobutanone with bis(2-methoxyethyl)aminosulfur trifluoride (Deoxo-Fluor) produced a gem-difluoride product together with a vic-difluoride bearing a cyclopropane ring. In contrast, the deoxyfluorination of the corresponding α-N-phthaloyl cyclopentanone produced the gem-difluoride only. Furthermore, the deoxyfluorination of the corresponding α-N-phthaloyl cyclohexanone
