- Display Note: Abstract: Expansion of the dipyridyl ligand from a five- to six-membered chelate for Ptᴵᴵ-catalyzed ethylene hydrophenylation provides an enhancement of catalyst activity and longevity. Mechanistic studies of [(dpm)Pt(Ph)(THF)]-[BAr₄][dpm=2,2-dipyridylmethane, and Ar = 3,5-(CF₃)₂C₆H₃] attribute the improved catalytic performance at elevated temperatures to a favorable change in entropy of activation with an increase in chelate ring size. The Ptᴵᴵ catalyst precursor [(dpm)PT(Ph)(THF)][BAr₄] is among the most active catalysts for ethylene hydrophenylation by a non-acid-catalyzed mechanism.
