概要 A series of lithium salts of bis ((perfluoroalkyl) sulfonyl) amides (1) with different chain lengths of perfluoroalkyl group and tris ((trifluoromethyl) sulfonyl) methanide (TTM) were prepared. The in...fluence of the polyfluoroalkyl chain length of the imide ions on the solubility of their benzyltrimethylammonium salts in water and the partition coefficients (α) in dichloromethane/water system were discussed with respect to the applicability of these anions to new types of anionic phase-transfer catalysts. The catalytic activities of these anions were compared with TFPB anions in the azo coupling reactions of p-nitrobenzenediazonium ions with N-ethylcarbazole in dichloromethane/water and dichloromethane/solid two-phase systems.続きを見る
