New Schiff bases of 1-vinyl- and 1-ethyl-substituted imidazoles and benzimidazoles were synthesized. The condensation reactions of 2-amino- and 2-formylimidazoles with 2-aminobenzimidazoles are virtually independent of the nature of the substituent (CH=CH2 or Et) at position 1 of the heterocycle. The structures of the azomethines synthesized were established by1H NMR and IR spectroscopy.
合成了新的 1-乙烯基和 1-乙基取代的咪唑和苯并咪唑的席夫碱。2-氨基-和2-甲酰基咪唑与2-氨基苯并咪唑的缩合反应实际上与杂环1位取代基(CH=CH2或Et)的性质无关。合成的偶氮甲碱的结构由1H NMR和IR光谱确定。
