Abstract

A direct transition-metal-free, convenient and highly regioselective synthesis of 2-alkyl/aryl sulfonyl tetrahydrofurans (THFs) has been achieved from THF and sodium sulfinates using K2S2O8 as a mild oxidant. This one-pot simple protocol involves an efficient radical cross coupling reaction in aqueous medium utilizing K2S2O8 as an inexpensive and easy to handle radical surrogate at room temperature.
