A handsome couple: Through the use of the simple Pd catalyst [Pd(tmpp)2Cl2] (tmpp=tris(2,4,6‐trimethoxyphenyl)phosphine) and THF/DMF as solvent, various aryl‐, heteroaryl‐, benzyl‐ and alkylaluminum reagents can be readily cross‐coupled with aryl or heteroaryl iodides, bromides, and nonaflates, and in special cases even with chlorides and triflates. This cross‐coupling tolerates free NH2 groups, aldehydes
一对英俊的夫妇:通过使用简单的Pd催化剂[Pd(tmpp)2 Cl 2 ](tmpp = tris(2,4,6-三甲氧基苯基)膦)和THF / DMF作为溶剂,各种芳基,杂芳基,苄基和烷基铝试剂可以很容易地与芳基或杂芳基碘化物,溴化物和壬二酸酯交叉偶联,在特殊情况下甚至与氯化物和三氟甲磺酸酯交叉偶联。这种交叉偶联可耐受游离的NH 2基团,醛,酮,酯和硝基官能团。
