Herein we report a Ni-catalyzed reductive transamidation of conveniently available N-acyl benzotriazoles with alkyl, alkenyl, and aryl nitro compounds, which afforded various amides with good yields and a broad substrate scope. The same catalytic reaction conditions were also applicable for N-sulfonyl benzotriazoles, which could undergo smooth reductive coupling with nitroarenes and nitroalkanes to
在此,我们报道了一种方便获得的N-酰基苯并三唑与烷基、烯基和芳基硝基化合物的 Ni 催化还原转酰胺基反应,该反应以良好的收率和广泛的底物范围提供了各种酰胺。相同的催化反应条件也适用于N-磺酰基苯并三唑,它可以与硝基芳烃和硝基烷烃进行平滑的还原偶联,得到相应的磺酰胺。

The palladium-catalyzeddirectarylation of furan, thiophene, pyrrole, or pyrazole derivatives bearing CONHR substituents on C2, C3, or C5 with arylbromides was studied. The use of KOAc as the base, DMAc as the solvent, and PdCl(C3H5)(dppb) as the catalyst was found to give regioselectively and without decarbamoylation the arylated heteroaromatics. Under these conditions, the amide substituent on
