Abstract

Epoxides are class of cyclic ether and have been extensively used in petrochemicals and pharmaceuticals industries as raw materials. Due to this reasons, development of the synthetic strategy of epoxides are getting enormous interest among the research chemists. In terms of “development of the synthetic strategy”, the use of a catalyst, especially, Schiff base-based complex is of potential interest due to alternative easy routes and significant advances in metal-mediated pathways giving rise to diverse degree of substrate–reagent interactions. In addition, the synthetic strategy that follows the 12 principles of green chemistry, particularly (i) reduce the use of organic solvent, especially toxic solvents, and (ii) increasing the use of catalysts to obtain selective and quick processes in terms of atom economy, are of great attention now a days. The present review encompasses the Schiff base-based molybdenum complexes as green catalyst in the epoxidation reaction. Molybdenum complexes have grown interest owing to lower cost, environmental protection and commercialization as well as its abundance in different metalloenzymes. On the other hand, molybdenum complexes speed up the O–O bond break of tert-butylhydroperoxide (TBHP); as a result, it accelerates the oxygen transfer process from TBHP to the olefin. This review mainly focused on the catalytic activity of molybdenum-based Schiff base complexes for the epoxidation reaction in water/solvent free condition.

基于希夫碱的钼络合物作为环氧化反应中的绿色催化剂:小视角。
环氧化物是一类环状醚,被广泛用作石油化工和制药行业的原材料。因此,环氧化物合成策略的开发受到了研究化学家的极大关注。就 "合成策略的开发 "而言,催化剂的使用,尤其是基于席夫碱的复合物,具有潜在的意义,因为它具有替代性的简便路线,并且在金属介导的途径方面取得了重大进展,从而产生了不同程度的底物-试剂相互作用。此外,遵循绿色化学 12 项原则的合成策略,尤其是(i)减少有机溶剂(尤其是有毒溶剂)的使用,以及(ii)增加催化剂的使用,以获得原子经济性方面的选择性和快速工艺,如今也备受关注。本综述介绍了在环氧化反应中作为绿色催化剂的希夫碱基钼络合物。钼络合物由于成本低、环保、商业化以及在不同金属酶中的丰富含量而越来越受到关注。另一方面,钼络合物可加速叔丁基过氧化氢(TBHP)O-O 键的断裂,从而加速从 TBHP 到烯烃的氧转移过程。本综述主要关注钼基席夫基地合物在无水/无溶剂条件下对环氧化反应的催化活性。
