(Rh2TPCP4) are sterically demanding and capable of controlling the site selectivity of C–H functionalization by means of C–H insertion with donor/acceptor carbenes. This study compares the structures and reactivity profiles of dirhodium triarylcyclopropanecarboxylates with dirhodium diarylcyclopropanecarboxylates. The absence of the third aryl group makes the catalysts less sterically demanding and
