Herein we report on the reactions of the stable LSiCl (1) and LGeCl (2) [L = PhC(NtBu)2] with L1Ge, [L1 = CH{(CCH 2)(CMe)(2,6-iPr2C6H3N)2}] (3) to yield 1-sila-5-germylene (4) and a 1,5-bis(germylene) (5). The reactions proceed through the 1,4 nucleophilic addition of the M-Cl (M = Si or Ge) to 3 without any modification of the oxidation state although the change of the oxidation state is thermodynamically more favorable. Compounds 4 and 5 were investigated by single crystal X-ray structural analyses, multi-nuclear NMR spectroscopy, and micro-analysis. Treatment of L1AlMe·thf (6) with 1 resulted in the formation of the 1-sila-5-aluminium complex (7). The complex contains a Si(ii) and an Al(iii) atom in the molecule. All reported reactions proceed without changing the oxidation states at the metal centers.
