Visible-light driven photoreactions using transition metal complexes as catalysts are currently a research hotspot in developing environmentally friendly sustainable processes. To develop a potential copper-based photocatalyst, a binuclear Cu(II) complex has been synthesized using a Mannich base ligand viz. 2,4-dichloro-6-((4-(2-hydroxyethyl)piperazin-1-yl)methyl)phenol (H2L). The photocatalyst has
使用过渡金属配合物作为催化剂的可见光驱动光反应目前是开发环保可持续工艺的研究热点。为了开发一种潜在的铜基光催化剂,使用曼尼希碱配体即合成了双核 Cu( II ) 配合物。2,4-二氯-6-((4-(2-羟乙基)哌嗪-1-基)甲基)苯酚( H 2 L )。已使用 ESI-MS 和单晶 X 射线衍射对光催化剂进行了表征。在可见光照射下,该催化剂可催化氢在N中的自转移-烷基化胺形成和苯甲醇氧化反应,转化率极好。通过 ESI-MS 光谱、UV-Vis 光谱和计算研究探索了催化反应的合理机制途径。
