Inside Cover: Pyridylidene‐Mediated Dihydrogen Activation Coupled with Catalytic Imine Reduction (Angew. Chem. Int. Ed. 33/2015)

The trapping of H 2 with a pyridylidene generated from a pyridinium salt and base is reported by A. Pfaltz, P. Mauleón et al. in their Communication on page 9542 ff. By coupling H 2 activation with subsequent hydride transfer to an imine, a catalytic process was established. Treatment of the N ‐phenylimine of phenyl trifluoromethyl ketone with N‐ mesityl‐3,5‐bis(2,6‐dimethylphenyl)pyridinium triflate and LiN(SiMe 3 ) 2 under 50 bar of H 2 resulted in high conversion into the corresponding amine.
