An acceptorless dehydrogenative methodology for the synthesis of amides, aldehydes and ketones from hemiaminal and alcohols in the presence of manganese(I) based photocatalyst is developed. Several aromatic, aliphatic, heterocyclic aldehydes and primary aryl amines as well as secondary alkyl amines were coupled, providing the corresponding amides. The methodology was also extended for dehydrogenation of various alcohols to get the corresponding carbonyls. The proposed catalytic cycle was supported by various control experiments as well as different analytical techniques such as NMR, IR and ESI-MS.

Photoredox (NN)Mn(I) 催化的无受体脱氢：酰胺、醛和酮的合成

开发了一种在锰 (I) 基光催化剂存在下从半缩醛胺和醇合成酰胺、醛和酮的无受体脱氢方法。几种芳香族、脂肪族、杂环醛和伯芳基胺以及仲烷基胺偶联，得到相应的酰胺。该方法还扩展到各种醇的脱氢以获得相应的羰基化合物。所提出的催化循环得到了各种控制实验以及不同分析技术（如 NMR、IR 和 ESI-MS）的支持。
