4,7-Dipyrrolidinyl-1,10-phenanthroline (DPPhen) was identified as an efficient ligand for copper catalysed selective aromatic N-arylation in water. N-Arylation of indoles, imidazoles and purines proceeds with moderate to excellent yields and complete selectivity over aliphatic amines. Aqueous medium and the possibility for low metal and ligand loadings give the process a benign environmental profile.
4,7-二吡咯烷基-1,10-菲蒽 (DPPhen) 被确定为一种高效的配体,用于在水中催化选择性芳香族氮芳基化的铜催化反应。吲哚、咪唑及嘌呤的氮芳基化反应以中等到优良的产率进行,并对脂肪胺具有完全的选择性。水相介质和低金属及配体用量的可能性使该过程具有良好的环境特征。
