Ni(acac)2 catalyzes the four-component connection reaction of trimethylaluminium (or diphenylzinc), isoprene, aromatic aldehydes and p-anisidine in this order and provides (E)-1-aryl-1-(p-methoxyphenyl)amino-3-methyl-3-hexenes (or (E)-1-aryl-1-(p-methoxyphenyl)amino-3-methyl-5-phenyl-3-pentenes) selectively in good yield.
Ni(acac)2催化三甲基铝(或二苯基锌)、异戊烯、芳香醛和对氨基茴香醚按此顺序的四组分连接反应,并选择性地以良好的产率提供(E)-1-芳基-1-(对甲氧基苯基)氨基-3-甲基-3-己烯(或(E)-1-芳基-1-(对甲氧基苯基)氨基-3-甲基-5-苯基-3-戊烯)。
