End‐On Nitrogen Insertion of a Diazo Compound into a Germanium(II) Hydrogen Bond and a Comparable Reaction with Diethyl Azodicarboxylate

A happy ending : The germanium(II) hydride [LGeH], where L=[HC{(CMe)(2,6‐ i Pr 2 C 6 H 3 N)} 2 ], reacts with a diazoalkane to form the hydrazone derivative (see picture). The reaction proceeds through the unprecedented end‐on nitrogen insertion of the diazo compound.
