Abstract

The synthesis of three novel Pd germylene complexes is reported. (Ph₃P)₂PdGe[N(SiMe₃)₂]₂ (1) was synthesized by ligand substitution of (Ph₃P)₄Pd, whereas (Et₃P)PdGe[N(SiMe₃)₂]₂ (2) and {appePdGe[N(SiMe₃)₂]₂}₂ (3b) (dppe = (diphenylphosphino)ethane) were synthesized by photolytic reduction of their corresponding phosphine oxalato complexes followed by addition of the germylene ligand. In solution, 3b exists in equilibrium with the monomeric dppePdGe[N(SiMe₃)₂]₂ (3a). The germylene ligand of 2 was found to be 1 order of magnitude more labile than the analogous Pt system and 2 orders of magnitude less labile than the analogous Ni system. The reactivity of these new palladium germylenes toward O₂ is described.
