opening and, subsequently, reductive cross-coupling of cycloketone oxime esters with thiosulfonate or seleniumsulfonate are reported, which involves C-C bond cleavage and C(sp3)-S or C(sp3)-Se bond formation. Notably, S-aryl/alkyl sulfonothioates and Se-alkyl seleniumsulfonothioates could be employed in this reaction to afford a variety of 1° and 2° alkyl sulfides, aryl sulfides, and 1° and 2° alkyl selenides
据报道,镍催化开环,然后环酮肟酯与硫代磺酸盐或硒代磺酸盐的还原性交叉偶联,涉及CC键断裂和C(sp3)-S或C(sp3)-Se键的形成。值得注意的是,在该反应中可以使用S-芳基/烷基磺基硫醚盐和Se-烷基硒基磺基硫磺酸盐,以一步得到多种1°和2°烷基硫化物,芳基硫化物以及1°和2°烷基硒化物。该策略的特点是易于获得的底物和温和的反应条件。
