A mild, simple, efficient and metal-free approach to β-keto sulfoxides utilising eosin Y as an organophotoredox catalyst has been developed. This general protocol offers a direct and rapid difunctionalization of alkenes using thiophenols and atmospheric oxygen at room temperature in a one-pot procedure. The utilisation of visible light and air (O2) as inexpensive, readily available, non-toxic and eco-sustainable
已经开发出一种温和,简单,有效且不含金属的方法,利用曙红Y作为有机光氧化还原催化剂来合成β-酮亚砜。该通用方案在室温下通过一锅法使用硫酚和大气中的氧气提供了烯烃的直接快速双官能化。可见光和空气(O 2)作为廉价,易于获得,无毒且生态可持续的试剂的利用使该协议与绿色化学要求兼容。
