Irradiation of mixtures of aryl perfluoroalkanesulfonates (RfSO3C6H4X-p, X = H, Cl and Me) (1) and aniline (2a), N,N-dimethylaniline (2b) or N,N-dimethylaniline (2c) results in the formation of 2-coupling products 3 and 4-coupling products 4. However, in the reactions of 2b and 2c, in addition to 3 and 4, arenes 5 and N-methylaniline (6a) or N-ethylaniline (6b) are also detected. The presence of p-dinitrobenzene
辐照芳基全氟链烷磺酸盐(R f SO 3 C 6 H 4 X- p,X = H,Cl和Me)(1)和苯胺(2a),N,N-二甲基苯胺(2b)或N,N-二甲基苯胺的混合物(2c)导致形成2-偶合产物3和4-偶合产物4。但是,在2b和2c的反应中,除了3和4外,还有芳烃5和N-甲基苯胺(6a)或N-乙基苯胺(6b)也被检测到。存在p -dinitrobenzene,卜吨2 NO和氢醌显著抑制反应。提出了一种光致电子转移机理。
