An efficient one-pot, three-component synthesis of vinyl sulfones via iodide-catalyzed radical alkenylation using aryl diazonium salts, terminal alkenes and DABSO is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive control experiments, we propose a plausible radical mechanism.

Paragraph 0061-0062, (2017/03/23)
The invention discloses a method for preparing substituted ethyl aryl sulfone. The method comprises the following steps: a compound shown in a formula II, a compound shown in a formula III and alkali are uniformly mixed in a solvent and are subjected to a coupling reaction, a compound shown in a formula I containing R2' as -CH2CH2R is obtained after the reaction is complete; or the method comprises the following steps: the compound shown in the formula II, ethyl propiolate and alkali are uniformly mixed in the solvent and then are subjected to the coupling reaction, and the compound shown in a formula I containing R2' as -CH=CH2=OOCH2CH3 is obtained after the reaction is complete. The method has the advantages of universality, convenience, simple reaction system, and mild reaction condition; the reaction can be amplified to a gram level, the reaction raw materials are simple and easily available, the used alkali and raw materials have the advantages of low cost and easy acquisition, the atom utilization rate is high, and solvent toxicity is low.
