A Rh(III)-catalyzed one-pot reaction of N-phenoxyacetamides, ketones, and hydrazines for a facile access to disubstituted and trisubstituted ethylenes is reported. In this method, various ketones are transformed into donor–donor diazo compounds, which engage in insertion with N-phenoxyacetamides, following β-H elimination under Rh(III) catalysis to generate (E)-polyaryl-substituted olefins. This chemistry
报道了Rh(III)催化的N-苯氧基乙酰胺,酮和肼的一锅反应,可轻松获得二取代和三取代的乙烯。在这种方法中,将多种酮转化为供体-供体重氮化合物,在Rh(III)催化下将β-H消除后,可与N-苯氧基乙酰胺插入以生成(E)-聚芳基取代的烯烃。这种化学物质具有简单的原料,温和的反应条件和良好的官能团耐受性。
