comparable salen ligands, three synthesized CuIINaI-complexes present efficient catalytic activities for the coupling and cyclization reaction of 1,2-diaminopropane with nitriles towards 2-imidazolines. The catalytic results show that salen ligands with an electron-donating substituent and small sterichindrance improve the catalytic activity.
基于各种可比的塞伦配体,三种合成的Cu II Na I配合物为1,2-二氨基丙烷与腈的偶合和环化反应提供了对2-咪唑啉的有效催化活性。催化结果表明,具有供电子取代基和小位阻的萨伦配体提高了催化活性。
