Radical cyanomethylation/arylation of arylacrylamides to access oxindoles with acetonitrile as the radical precursor is described. This reaction involves dual C–H bond functionalization, including the sp3 C–H of acetonitrile and the sp2 C–H of the phenyl group. A variety of functional groups, such as methoxy, ethyloxy carbonyl, chloro, bromo, iodo, nitro, trifluoromethoxy and trifluoromethyl groups
描述了芳基丙烯酰胺的自由基氰基甲基化/芳基化以使用乙腈作为自由基前体来获得羟吲哚。该反应包括双C-H键的官能化,包括SP 3乙腈和C-H的SP 2的苯基的C-H。很好地耐受各种官能团,例如甲氧基,乙氧基羰基,氯,溴,碘,硝基,三氟甲氧基和三氟甲基。
