Transfer hydrogenation plays an important part in organic chemistry. Recently, strong Lewis acids like B(C 6 F 5 ) 3 have been introduced as a catalyst for these reactions. We successfully employed the Lewis acid (C 2 F 5 ) 3 PF 2 as a catalyst in the transfer hydrogenation between 1,3,5‐trimethylcyclohexa‐1,4‐diene and 1,1‐diphenylethylene. Surprisingly, the treatment of the diene alone with a catalytic amount of (C 2 F 5 ) 3 PF 2 led to a quantitative dismutation to mesitylene and 1,3,5‐trimethylcyclohexane. With B(C 6 F 5 ) 3 , there was a solvent‐dependency: in CH 2 Cl 2 mainly the dismutation products were obtained, while in toluene the evolution of H 2 was observed. Additionally, the catalytic activity of various perfluoroalkylated germanes and silanes was tested.
