An efficient Co-catalyzed 1,4-addition reaction of alkyl/aryl triflates and tosylates with activated alkenes is described. In this reaction, air-stable cobalt(II) complex, mild reducing agent Zn and simple proton source (H2O) are used. A radical mechanism for the addition of alkyl tosylates to activated alkenes is likely involved.
描述了烷基/芳基三氟甲磺酸酯和甲苯磺酸酯与活化的烯烃的有效的共催化的1,4-加成反应。在该反应中,使用了空气稳定的钴(II)配合物,温和的还原剂Zn和简单的质子源(H2O)。可能存在将烷基甲苯磺酸酯加成到活化烯烃上的自由基机理。
