噻唑硫酮因具有独特的生物活性,使其在医学和杂环化学等领域有着广泛的应用,从而引起了科研工作者的研究兴趣。本文以离子液体1-丁基-2,3-二甲基咪唑鎓醋酸盐(Bmmim OAc)为催化剂,2-芳氨基乙醇和二硫化碳为起始原料,一步缩合合成3-芳基-2-噻唑硫酮。以2-苯氨基乙醇和二硫化碳的反应为模型,考察了一系列离子液体的催化活性。发现只有阴离子为醋酸根的离子液体才具有催化活性,这可能是由醋酸根的碱性所导致的。在这些阴离子为醋酸根的离子液体中,Bmmim OAc的催化活性最高。以其为催化剂,系统考察了反应时间、反应温度、催化剂用量以及二硫化碳和2-苯氨基乙醇摩尔比对该反应的影响。得到最优的反应条件:反应时间6 h、反应温度130℃、10%的Bmmim OAc用量以及5:1的二硫化碳和2-苯氨基乙醇摩尔比。在该反应条件下,目标产物3-苯基-2-噻唑硫酮的收率达到了97%。以不同的2-芳氨基乙醇为原料,考察了该反应的普适性。结果表明无论是具有给电子基团、吸电子基团或较大空间位阻的2-芳氨基乙醇均可顺利地与二硫化碳反应生成相应的3-芳基-2-噻唑硫酮,且分离收率高达83%–95%。核磁共振波谱和质谱分析表明反应过程中Bmmim OAc的醋酸根阴离子可以自发地与二硫化碳反应生成硫代醋酸根阴离子,因此离子液体1-丁基-2,3-二甲基咪唑鎓硫代醋酸盐(Bmmim COS)可能是2-芳氨基乙醇和二硫化碳反应的催化剂。通过核磁共振波谱研究了Bmmim COS与反应底物2-苯氨基乙醇和二硫化碳之间的相互作用,发现Bmmim COS与2-苯氨基乙醇之间存在氢键相互作用。在反应过程中硫代醋酸根阴离子通过氢键作用活化2-苯氨基乙醇,从而促进反应高效进行。基于表征结果,提出了一个可能的反应机理。首先,Bmmim OAc自发地与二硫化碳反应生成Bmmim COS。然后,Bmmim COS中的硫代醋酸根阴离子通过氢键作用活化2-苯氨基乙醇。随后,活化的2-苯氨基乙醇与二硫化碳反应生成中间体。最后,中间体分子内环化生成目标产物3-苯基-2-噻唑硫酮。2喀土穆大学教育学院化学系,思图曼406。
