  • Title: Pd-catalyzed intramolecular acylation of aryl bromides via C-H functionalization: a highly efficient synthesis of benzocyclobutenones.
    Author: Alvarez-Bercedo P, Flores-Gaspar A, Correa A, Martin R.
    Journal: J Am Chem Soc; 2010 Jan 20; 132(2):466-7. PubMed ID: 20038097.
    Abstract:
    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.
