The cationic [RuCl(PNNP)] catalysts containing tetradentate ligands with a P 2 N 2 donor set (PNNP) show strong electronic effects in the cyclopropanation of para-substituted styrenes. The reactivity trend confirms that the carbene transfer to the olefin has electrophilic character. Linear free-ener
