% CBZ6)-catalyzed reductive (pinacol) coupling of aldehydes, ketones, and imines has been developed. Irradiated by purple light (407 nm) using triethylamine as an electron donor, a variety of 1,2-diols and 1,2-diamines could be prepared. The oxidation potential of the excited state of CBZ6 is established as −1.92 V (vs saturated calomel electrode (SCE)). The relative high reductive potential enables
已经开发了可回收的有机光还原剂(1摩尔%CBZ6)催化的醛,酮和亚胺的还原(频哪醇)偶联。使用三乙胺作为电子供体,在紫色光(407 nm)照射下,可以制备各种1,2-二醇和1,2-二胺。CBZ6的激发态的氧化电位为-1.92 V(相对于饱和甘汞电极(SCE))。较高的还原电位使得羰基化合物及其衍生物能够还原偶联。CBZ6可以克量制备,并且对酸/碱或空气稳定。可用于大规模光还原合成,反应后高收率回收。
