A large series of 1,2‐diaryl‐benzimidazole and 2‐aryl‐1H‐benzimidazolederivatives were synthesized with slight differences using both microwave irradiation and conventional heating methods. Usually higher yields and time reactions reduction were obtained with the former method. All compounds were assayed for their in vitro ability to inhibit humancyclooxygenases, and most of them showed an encouraging

achieved. The compounds have been characterized by IR, NMR, micoranalysis, and GC-MS. The reaction for the formation of benzimidazoles has been monitored with 1 H NMR and IR. The crystal structures of two derivatives, 2-(2-chlorophenyl)-1 H -benzimidazole and 2-(1 H -benzimidazol-2-yl)-4-nitrophenol, are presented. A study of the DPPH scavenging activity of these compounds showed that 2-(1 H -benzimidazol-2-yl)phenol
已经实现了碱催化的醛向苯并咪唑的转化。该化合物已通过IR,NMR,微量分析和GC-MS进行了表征。用1 H NMR和IR监测形成苯并咪唑的反应。给出了两种衍生物2-(2-氯苯基)-1H-苯并咪唑和2-(1H-苯并咪唑-2-基)-4-硝基苯酚的晶体结构。对这些化合物的DPPH清除活性的研究表明,2-(1 H-苯并咪唑-2-基)苯酚(2),2-对甲苯基-1 H-苯并咪唑(3)和2-(4-甲氧基苯基) -1 H-苯并咪唑(7)的IC 50值为1974、773和800 µM。关键词:苯并咪唑,邻苯二胺,醛,碱催化,DPPH清除活性。化学 Soc。埃塞俄比亚。2018,32(2),271-284。DOI:https://dx.doi.org/10.4314/bcse.v32i2.8
