A novel and efficient electrochemical radical δ-H sulfonylation reaction of para-quinone methides (p-QMs) and sodium sulfinates has been achieved under common laboratory conditions. In this strategy, a new C(sp2)-S bond was constructed for the synthesis of 4-((aryl,arylsulfonyl)methylene)-2,5-cyclohexadiene derivatives with a broad substrate scope, good functional group tolerance, and mild conditions. Further studies showed that the reaction had an excellent regional selectivity.

A coupling reaction between sulfonyl radicals and silver-based carbenes has been well established. This simple radical-carbene coupling (RCC) process provided an efficient approach to a variety of β-carbonyl arylsulfones from sodium arylsulfinates and diazo compounds, and was characterized by wide substrate scope, easy scale-up, simple manipulation, accessible starting materials, and mild reaction conditions.

We disclose here the first iodine/tert-butyl hydroperoxide (I2/TBHP)-mediated benzylic C–H sulfonylation of phenol derivatives. This new methodology provides an economic, operationally simple and metal-free approach toward C(sp3)–S bond formation with medium to excellent yields at room temperature. Moreover, a novel sulfonylative and peroxidative bifunctionalization of phenol derivatives was also achieved by changing the amount of the oxidant. The reaction mechanism is exemplified via a radical pathway. (Figure presented.).
