α-bromocarbonyls where aerial oxygen played a role of an oxidant to install the keto-oxygen functionality. This unique process is compatible with both internal and terminal olefins and tolerates a diverse array of functional groups (ketone, ester, amide, diketones, ketoester, and malonate). This process is mild and environmentally friendly and deals with greener oxidants like oxygen, affording 1,4-ketocarbonyls as
在α-溴羰基的帮助下,已经公开了乙烯基芳烃的有机染料催化的可见光促进的酮羰基化方案,其中空气中的氧起氧化剂的作用以安装酮氧官能团。这种独特的方法可与内部和末端烯烃兼容,并能耐受各种官能团(酮,酯,酰胺,二酮,酮酸酯和丙二酸酯)。此过程温和且环保,可处理较绿色的氧化剂,例如氧气,可提供1,4-酮羰基化合物作为增值的最终产品。
