simple ketones via diazo compounds, including diazo‐amides and ‐phosphonates, using a recyclable reagent in‐flow, are transient but versatile electrophiles for heteroatom alkylation reactions and for epoxide formation. The method produces no organic waste, with the only by‐products being water, KI and nitrogen, without the attendant hazards of isolation of intermediate diazo compounds.
高活性金属卡宾,是通过简单的酮类通过重氮化合物(包括重氮酰胺和膦酸酯)通过重氮化合物(使用可循环利用的试剂流入)生成的,是一种瞬态但通用的亲电子试剂,可用于杂原子烷基化反应和环氧化物的形成。该方法不产生有机废物,唯一的副产品是水,KI和氮气,并且没有分离中间体重氮化合物的伴随危险。
