An iron-catalyzed direct aerobic α,β-dehydrogenation of carbonyls has been reported. The combination of tert-butyl nitrite and N-hydroxyphthalimide worked as the organo cocatalyst system; thus, no extra transition metal reagents are required. A large variety of lactams and flavanones as well as lactone and thiochromen-4-one could be produced via this method in high yields.
铁催化的羰基直接需氧 α,β-脱氢反应已被报道。亚硝酸叔丁酯与N-羟基邻苯二甲酰亚胺组合作为有机助催化剂体系;因此,不需要额外的过渡金属试剂。通过该方法可以高产率地生产多种内酰胺和黄烷酮以及内酯和四苯硫色酮。
