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.
