compounds in a less costly, compact, and greener manner from cheap and readily available reagents is highly desirable in modern synthetic chemistry. Herein, we report a straightforward synthesis of benzimidazoles by reductive coupling of o-dinitroarenes with aldehydes in the presence of molecular hydrogen. An innovative molecular cluster-based synthetic strategy that employs Mo3S4 complexes as precursors
现代合成化学非常需要开发更可持续的催化工艺,以更便宜、更紧凑、更环保的方式从廉价且易于获得的试剂制备 N-杂环化合物。在此,我们报告了在分子氢存在下通过邻二硝基芳烃与醛的还原偶联直接合成苯并咪唑。采用 Mo 3 S 4配合物作为前体的基于分子簇的创新合成策略已被用于设计缺硫二硫化钼 (MoS 2) 型材料在自然发生的边缘位置和沿典型的非活动基面显示结构缺陷。通过应用这种催化剂,即使在存在氢化敏感官能团(如双碳-碳键和三碳-碳键)的情况下,也可以通过这种直接氢化偶联方案选择性合成多种功能化的 2-取代苯并咪唑,包括生物活性化合物、腈和酯基团、卤素以及各种类型的杂芳烃。
