PtII complexes supported by dipyridyl ligands have been demonstrated to catalyze olefin hydroarylation. Herein, studies on the influence of dipyridyl motif variation are reported. Increasing the chelate ring size of dipyridyl-ligated PtII complexes from five-to six-membered rings by replacing 4, 4′-di-tert-butyl-2, 2′-bipyridine with 2, 2′-dipyridylmethane has been shown to increase catalytic activity and longevity for catalytic ethylene ...
