enhance the scope of our cyclization–anion capture methodology, is introduced and exemplified by a wide variety of catalytic cyclization–carbonylation–anion capture processes employing hydride, organostannanes and NaBPh4 as anion capture agents. Mono- and bis-cyclization processes forming 5- and 6-membered rings are described, all of which employ CO at atmospheric pressure. Cyclocarboformylation processes
使用氢化物,有机锡和NaBPh 4作为阴离子捕获剂的各种催化环化-羰基化-阴离子捕获工艺引入并举例说明了继电器开关反应物的概念,该概念极大地扩展了我们的环化-阴离子捕获方法的范围。描述了形成5元和6元环的单环和双环化方法,所有这些方法均在大气压下使用CO。环羰基甲酰化工艺提供了有趣的加氢甲酰化类似物。
