Abstract
N-(Trifluoromethylsulfonylimino)di-and-trifluoromethanesulfinimidoyl chlorides RS(=NSO2CF3)Cl (R = CF3, CHF2) react with potassium fluoride in 1,2-dimethoxyethane with formation of the corresponding N,N′-bis(trifluoromethylsulfonyl)fluoromethanesulfinimidamide potassium salts RS(=NSO2CF3)NSO2CF3 −K. Analogous methanesulfinimidoyl and fluoromethanesulfinimidoyl chlorides (R = CH3, CH2F) fail to react with KF under similar conditions. Treatment of trifluoromethanesulfenamides CF3SNR2 with N,N-dichlorotrifluoromethanesulfonamide CF3SO2NCl2 leads to N,N-disubstituted N′-(trifluoromethylsulfonyl)trifluoromethanesul-finimidamides CF3S(=NSO2CF3)NR2. The reaction of N,N-dimethyl-N′-(trifluoromethylsulfonyl)trifluoromethanesulfinimidamide (R = CH3) with gaseous hydrogen chloride in diethyl ether gives sulfinimidoyl chloride CF3S(=NSO2CF3)Cl which could not be obtained by imination of CF3SCl.
