Abstract: The series of Ptᴵᴵ complexes [(˟bpy)Pt(Ph)(THF)][BAr'₄] (˟bpy = 4,4'-X-2,2'-bipyridyl, X = OMe, ᵗBu, H, Br, CO₂Et, NO₂; Ar' = 3,5-bis(trifluoromethyl)phenyl) are catalyst precursors for ethylene hydrophenylation. The bipyridyl substituent provides a tunable switch for catalyst selectivity that also has significant influence on catalyst activity and longevity. Less electron donating 4,4'-substituents increase the propensity toward styrene formation over ethyl-benzene.
