Iodine-catalyzed C–H/S–H oxidative coupling: from 1,3-diketones and thiophenols to β-dicarbonyl thioethers†
Abstract
A novel method on iodine-catalyzed oxidative coupling between 1,3-diketones and thiophenols to form β-dicarbonyl thioethers was developed. The C–S bond was supposed to be formed via a radical substitution pathway instead of the usual nucleophilic substitution one.
