lesser crowding of the di-isopropylphosphino-substituted catalysts. Experimentally determined kineticisotopeeffects in conjunction with DFT-based analysis support a dehydrogenation mechanism involving initial pre-equilibrium oxidative addition of the amine α-C-H bond followed by rate-determiningelimination of the β-C-H bond.
