## Abstract The catalytic hydrogenation of (2__R__, 10__R__)‐2, 10‐diamino‐5, 5, 7‐trimethyl‐4, 8‐diaza‐7‐undecenenickel(II) yields two products when the reaction is performed in the presence of ethylenediamine, but only one, when ethylenediamine is absent. The stereochemistry of the reaction is di
