A catalyst based on the readily available Cu₂S/TMEDA system using a stable copper(I) source was developed for the Chan-Lam cross-coupling reaction. The capability of the catalyst was demonstrated with 1H-benzo[d]imidazol-2(3H)-one, 1H-benzo[d]imidazole, and 1H-imidazole together with electron-deficient, electron-rich, and sterically demanding boronic acids at room temperature in the presence of atmospheric oxygen to give the cross-coupling products in moderate to excellent yields. In addition, the coupling reaction of 1H-benzo[d]imidazole with several pinacol or neopentylglycol boronates indicated further potential of the catalyst. The reaction conditions tolerate the hydroxyl and bromo functional groups. The catalytic system also enables to synthesize the mono-N-substituted anilines from primary aliphatic amines. However, the two model compounds for the secondary and aromatic amines, piperidine and aniline, do not react. Two sterically demanding products with the restricted CN bond rotation, synthesized by the N-arylation of 1H-benzo[d]imidazol-2(3H)-one with o-tolylboronic acid, enabled to confirm the atropisomers prepared by the Chan-Lam cross-coupling reaction. Furthermore, an example of one-pot Chan-Lam and Suzuki-Miyaura reaction has been reported.

基于Chan-Lam交叉偶联反应，开发了一种基于使用稳定铜（I）源的现成Cu ₂ S / TMEDA系统的催化剂。用1 H-苯并[ d ]咪唑-2（3 H）-1，1 H-苯并[ d ]咪唑和1 H-咪唑以及缺电子，富电子和在室温下，在大气氧的存在下，对空间需求量高的硼酸，以中等至极好的收率得到交叉偶联的产物。另外，1 H-苯并[ d]的偶联反应]咪唑与几种频哪醇或新戊二醇硼酸酯表明该催化剂的进一步潜力。反应条件容许羟基和溴官能团。该催化体系还能够由伯脂族胺合成单-N-取代的苯胺。但是，仲胺和芳族胺的两种模型化合物哌啶和苯胺不会反应。两个空间要求的产品与受限Ç N键的旋转，通过将合成的Ñ 1的-arylation ħ -苯并[ d ]咪唑-2（3 H ^） -酮与ö-甲苯磺酸，能够确认由Chan-Lam交叉偶联反应制得的阻转异构体。此外，已经报道了一锅Chan-Lam和Suzuki-Miyaura反应的例子。
