Abstract A highly efficient and simple protocol for the N-arylation of some hindered aza-heterocycles in water has been developed with readily available basic copper carbonate as the catalyst using bis(3,5-dimethyl-1H-pyrazol-1-yl)methane as ligand. This mild catalytic system possesses excellent tolerance for a large variety of functional groups. A total of 11 previously unknown coupling products have
摘要 以易得的碱式碳酸铜为催化剂,使用双(3,5-二甲基-1H-吡唑-1-基)甲烷,开发了一种高效且简单的方法,用于在水中一些受阻氮杂杂环的 N-芳基化。作为配体。这种温和的催化体系对多种官能团具有极好的耐受性。通过这种方法共合成了 11 种以前未知的偶联产物。图形概要
