A new catalyst system for the intramolecular acylation of aldehydes with aryl bromides via C-H functionalization is described. The transformation is distinguished by a remarkable functional group tolerance and hence allows for the synthesis of a wide variety of highly functionalized benzocyclobutenones with a diverse set of substitution patterns from simple and easily accessible precursors.

An efficient copper-catalyzed intramolecular N-arylation was performed by using substituted 2-(2-bromoaryl)acetamide with small amount of Cu2O and benzene-1,2-diamine as catalytic system under aerobic conditions, which provided good to excellent yields of oxindoles with tolerance of a wide variety of substrates.
