β-Keto sulfones were obtained in good to excellent yields (73–94 %) directly from unactivated olefins by employing inexpensive sodium arenesulfinate salts as sulfonylating agents and K2S2O8 as a radical initiator in open flasks and aqueous media at room temperature under transition-metal-free conditions. The reported oxidative sulfonylation protocol is highly practical and environmentally benign, as
通过使用廉价的芳烃亚磺酸钠盐作为磺酰化剂和 K2S2O8 作为自由基引发剂,在室温下,在室温下,在开放烧瓶和水性介质中,从未活化的烯烃中以良好的收率(73-94%)获得 β-酮砜。免费条件。报道的氧化磺酰化方案非常实用且对环境无害,这一点由极其温和的反应条件证明。
