Room‐temperature sub‐mol % Ullmann amination has been realized, promoted by the organic ionic base TBPM (14 examples). In addition, the stability and application of ammonium and phosphonium based organic ionic bases at higher temperatures was investigated, leading to a new protocol for the activation of structurally complex amines.
通过有机离子碱
TBPM促进了室温亚摩尔%的Ullmann胺化反应(14个实例)。此外,研究了
铵和phospho基有机离子碱在更高温度下的稳定性和应用,从而导致了一种用于活化结构复杂胺的新方案。
