selective, efficient, and simple method for direct transamidation of thioamides with amines, promoted by commercially available acetophenone under metal-/solvent-free conditions. The reaction tolerated a wide range of functional groups and substrates, including single- or double-thioamides, benzylamines, or alkyl/cycloalkyl-substituted aliphatic amines. The present protocol can be applied to gram-scale in
在此,我们开发了一种高选择性、高效且简单的方法,用于在无金属/溶剂的条件下通过市售苯乙酮促进硫代酰胺与胺的直接转酰胺基化。该反应可耐受多种官能团和底物,包括单硫代酰胺或双硫代酰胺、苄胺或烷基/环烷基取代的脂肪胺。本协议可以以良好的产量应用于克级。此外,双转酰胺基产物的 Pt-/Ni-配合物的产率也很高。光物理性质的研究表明,Pt配合物的荧光光谱显示出以550-750 nm为中心的发射带,并在紫外灯(365 nm)照射下呈现红色荧光。
