C-H Functionalization of Cyclopropanes: A Practical Approach Employing a Picolinamide Auxiliary

A Pd-catalyzed, picolinamide-enabled, and efficient C-H arylation of cyclopropanes is described. The reaction can be promoted by either a silver additive or catalytic pivalic acid in the presence of a carbonate base. Various aryl iodides can be employed as coupling partners, providing exclusively cis-substituted cyclopropylpicolinamides.
