Fu, Ying published the artcileCharge-Transfer Complex Promoted Regiospecific C-N Bond Cleavage of Vicinal Tertiary Diamines, Recommanded Product: 4-Chloro-3-(trifluoromethyl)benzenesulfonyl Chloride, the publication is Advanced Synthesis & Catalysis (2018), 360(18), 3502-3506, database is CAplus.
A catalyst-free, charge-transfer complex promoted coupling of sulfonyl chlorides RSO2Cl (R = cyclopropyl, Ph, 3,5-F2C6H3, 2-naphthyl, 2-thienyl, 8-quinolinyl, etc.) with vicinal tertiary diamines R1R2NCH2CH2NR1R2 (R1 = R2 = Me, Et, n-Pr, i-Pr, i-Bu; R1 = Me, R2 = Ph, 3-MeC6H4, etc.; R1R2N = 1-pyrrolidinyl, 4-morpholinyl) to generate sulfonamides RSO2NR1R2 is presented. Mechanistic studies showed that these reactions proceed via charge transfer of vicinal tertiary diamines to sulfonyl chlorides, forming the unstable sulfonyl quaternary ammonium-like complexes which induce the regiospecific intramol. C-N bond cleavage of vicinal tertiary diamines.
