Phenacylideneaniline was formed by Et3N-catalyzed elimination reaction of the hydroxylamine obtained from silyl enol ether 5a and nitrosobenzene (6). By this method, one-pot procedure was possible for cycloaddition reactions of the related anils. From these reactions, it was revealed that 6 reacted efficiently with a silyl enol ether having a π-donating substituent.
通过从甲硅烷基烯醇醚 5a 和亚硝基苯 (6) 中获得的羟胺的 Et3N 催化消除反应,形成了苯胺。通过这种方法,相关苯胺的环加成反应可以进行一锅法。从这些反应可知,6与具有π供体取代基的甲硅烷基烯醇醚有效地反应。
