Halogen Selectivity in Nickel Salt-Catalyzed Cross-Coupling of Aryl Grignard Reagents with Bromochlorobenzenes a Novel Synthetic Method of Unsymmetrical Terphenyl
Abstract The reactions of aryl Grignardreagents with p- and m-bromochlorobenzenes catalyzed by non-ligated NiCl2 give selectively chlorobiphenyl derivatives. By the stepwise reaction, an unsymmetrical terphenyl was synthesized in a good yield.
A bulky carboxylic acid bearing one 1-adamantylmethyl and two methyl substituents at the α-position is demonstrated to work as an efficient carboxylate ligand source in Pd-catalyzed intermolecular C(sp2)–H bond arylation reactions.
