Transition metal germylene complexes as hydrogenation catalysts: The synthesis of a rare bis(amino)germane

Litz,Bender IV,Kampf,Holl

, p. 496 - 498 (1997)

Mild conditions avoid the common problem of Ge-N bond scission in the stoichiometric and catalytic synthesis of a rare example of a stable bis(amino)germane from Group 10 metal - germylene complexes [Eq. (a), R = Et, Ph]. The reaction generates an interesting GeH2 building block.
