(hetero)aryl/alkenyl halides (Br, I) is described here. The method relies on using some newly developed oxalamide ligands, and gives coupling products in great diversity. Since the coupling products can be conveniently transformed into the corresponding α-(hetero)aryl amines, ketones, carboxylic acids and aldehydes, our method provides a highly competitive approach for preparing these compounds from readily
A general protocol for the Pd-catalyzed-arylation of nitroalkanes is described. Substituted aryl bromides as well as aryl chlorides can be coupled efficiently with a variety of nitroalkanes under mild conditions to selectively yield the monoarylated products. This method tolerates a number of functional groups including ketones, esters, and olefins. Notably, the arylation of nitroalkanes can be effected chemoselectively over ketone and ester arylation.
