実験手順

Imines were hydrogenated using in situ-generated complex 2. Hydrogenation of N-benzylidene benzylamine proceeded under 4 atm H2 at 60° C. to afford dibenzylamine in 84% isolated yield using 2 mol % of complex 2 (Table 2, entry 13). N-Benzylidenemethylamine and N-benzylideneaniline were also hydrogenated by the cobalt catalyst, affording N-benzyl methyl amine and N-benzylaniline in good yields (Table 2, entries 14 and 15). Previous examples of cobalt-catalyzed imine hydrogenation are scarce.
