YieldReaction ConditionsOperation in experiment
60% With pyrrolidinodifluorosulfiniumtetrafluoroborate; triethylamine tris(hydrogen fluoride) In dichloromethane at 20℃; for 3 h; Inert atmosphere General procedure: To a solution of triethylamine trihydrofluoride (1equiv.) in dichloromethane (2mL) at room temperature was added the N,N-disubstituted aminodifluorosulfinium tetrafluoroborate (1.5equiv.) followed by 1,4-dioxaspiro[4.5]decan-8-one (1.0mmol, 1equiv.). After 3h of stirring under nitrogen, the reaction mixture was quenched at room temperature with a 5percent aqueous sodium bicarbonate solution, stirred for 15min, and the resulting mixture was extracted twice using dichloromethane. The organic phases were combined, dried over sodium sulfate and solvents were evaporated under low-vacuum at 40°C. NMR yield was calculated by integration of 19F NMR and/or 1H NMR signals of the resulting crude material+internal standard (2-fluoro-4-nitrotoluene).
