3′-diaryl-3,3′-diphthalides by dehalogenation of o-keto carboxylicacid pseudochlorides is implemented. The feature of the new protocol is that the reaction is carried out in the presence of a zero-valent nickel complex catalyst generated in situ by mixing zinc powder, nickel(II) chloride, triphenylphosphine, and 2,2′-bipyridine. Along with the target dimerization products of pseudochlorides, minor products were
A convenient method for the synthesis of 3-aryl isoindolinones via TfOH catalyzed C–H functionalization of arenes with 2-formylbenzonitriles is developed.
