月前,中科院化学研究所科研人员在CO2化学转化方面取得重要进展,研究人员通过构筑不同催化体系,发展了基于邻苯二胺或邻硝基苯胺、CO2和H2三组分反应合成苯并咪唑的绿色新途径,“一锅法”制得了苯并咪唑;以离子液体[HDBU][OAc]为溶剂和催化剂,使邻苯二胺与CO2直接羰基化反应生成苯并咪唑酮;采用商业Pd/C和有机碱DBU{1,8-二氮杂环[5,4,0]十一烯-7}的协同催化,发展了基于碘苯、CO2和聚甲基氢硅氧烷(PMHS)反应直接合成苯甲醛的新方法。 Months ago, CAS researchers made significant progress in chemical conversion of CO 2. Researchers have developed different catalysts based on o-phenylenediamine or o-nitroaniline, and the combination of CO2 and H2 to synthesize benzimidazole Of the green new way, “one pot method ” obtained benzimidazole; Ionic liquid [HDBU] [OAc] as a solvent and catalyst, o-phenylenediamine and carbon dioxide direct carbonylation reaction to generate benzimidazolone; using The synergistic catalysis of commercial Pd / C and the organic base DBU {1,8-diazabicyclo [5,4,0] undecene-7} has led to the development of catalysts based on iodobenzene, CO2 and polymethylhydrosiloxane PMHS) for the direct synthesis of benzaldehyde.
