    • In the absence of the Ru catalyst system, a partial conversion of 1 and 2 into imine 4 was observed. With [Ru(cod)Cl2]n alone, a lower yield of amine 3 was obtained.

    • The alkylation failed when aliphatic amines were used; the reduction to the amine did not occur, and the corresponding imines were obtained in high yield.
