An iron(III) salt, (Z)-1,2-bis(diphenylphosphino)ethene or its electron-rich congener, (Z)-1,2-bis[bis(4-methoxyphenyl)phosphine]ethene, and a zinc(II) salt catalyze the arylation, heteroarylation, and alkenylation of propionamides possessing an 8-quinolylamide group with organoborate reagents in the presence of 1,2-dichlorobutane as oxidant at 70 °C. Stoichiometric experiments provided evidence for
铁(III)盐,(Z)-1,2-双(
二苯基膦基)
乙烯或其富电子同源物,(Z)-1,2-双[双(4-
甲氧基苯基)膦]
乙烯和
锌(II)盐在70°C下以
1,2-二氯丁烷为
氧化剂,用有机
硼酸盐试剂催化具有8-
喹啉酰胺基的丙
酰胺的芳基化,杂芳基化和
烯基化反应。
化学计量学实验提供了证据证明
有机铁(III)物种是C–H活化和C–C键形成的关键
中间体。
