The frustrated Lewis pair (FLP)‐catalyzed hydrogenation and deuteration ofN‐benzylidene‐tert‐butylamine (2) was kinetically investigated by using the three boranes B(C6F5)3(1), B(2,4,6‐F3‐C6H2)3(4), and B(2,6‐F2‐C6H3)3(5) and the free activation energies for the H2activation by FLP were determined. Reactions catalyzed by the weaker Lewis acids4and5displayed autoinductive catalysis arising from a higher free activation energy (2 kcal mol−1) for the H2activation by the imine compared to the amine. Surprisingly, the imine reduction using D2proceeded with higher rates. This phenomenon is unprecedented for FLP and resulted from a primary inverse equilibrium isotope effect.
