四甲基胍分别与间苯二甲酰氯和间苯二磺酰氯反应合成了间苯二甲酰四甲基胍和间苯二磺酰四甲基胍 ,其结构经元素分析 ,IR ,1HNMR和EI MS表征。核磁滴定研究表明 ,上述化合物可与二酸形成 1∶1化学计量络合物 ,其络合常数在 5 .3 3× 1 0 5～ 3 .68× 1 0 5。
Tetramethylguanidine was reacted with isophthaloyl dichloride and m-phenylene disulfonyl chloride to synthesize tetramethylguanidyl isophthaloylate and isomethanedisulfonyl tetramethylguanidine. The structures were characterized by elemental analysis, IR, 1HNMR and EI MS characterization. The results of NMR showed that the above compounds could form 1: 1 stoichiometric complex with diacid with the complex constants of 5.33 × 105 ~ 3.68 × 105.
