harness aromatic isocyanides as visible-light photocatalysts in the α-amino C(sp3)–H functionalization is herein presented. Actually, the three-component cross-dehydrogenative coupling of aromatic tertiary amines with isocyanides and water leads to amide products under very mild conditions in high yields and with a good substrate scope. While the reaction with aromatic isocyanides proceeds upon direct
本文提出了在 α-氨基 C(sp 3 )-H 官能化中利用芳族异氰化物作为可见光光催化剂的可能性。实际上,芳族叔胺与异氰化物和水的三组分交叉脱氢偶联在非常温和的条件下以高产率和良好的底物范围产生酰胺产物。虽然与芳香族异氰化物的反应在直接光激发下进行,但脂肪族异氰化物能够与芳香胺形成光敏电子-供体-受体复合物。此外,芳香族异氰化物的催化负载的使用促进了N的氧化偶联-苯基-1,2,3,4-四氢异喹啉具有一系列不同的(原)亲核试剂,产率良好至极好,从而为开发新型高度可调的有机可见光光催化剂提供了概念验证.
