series of N-heterocycliccarbene-palladium(II) chlorides-1-methylindazole and -1-methylpyrazole complexes was successfully synthesized and fully characterized by X-ray single crystal diffraction. In addition, initial investigations of their catalytic activity showed that they were efficientcatalysts in the C–N coupling of primary and secondary amines with aryl chlorides at low catalyst loadings.
Provided herein are nickel(O) catalysts that are stable when exposed to air and can be used to catalyze the formation of a C-C, C-O, or C-N bond.
提供于此的镍(0)催化剂在暴露于空气时稳定,并且可用于催化形成C-C、C-O或C-N键。

bis(diimidazolylidene) NHC ligands and two non coordinating bromide counter ions in tetradentate C4 fashion. A survey of their catalytic activity in Buchwald−Hartwig amination has been performed. The newly synthesized complexes also catalyzed the amination of aryl chlorides in the presence of KOtBu. Various aryl chlorides and amines can react smoothly to give the corresponding aminated products in moderate to high yields
