The synthesis of germanium(II) 2‐tert‐butyl‐4‐methyl‐6‐(oxidomethyl)phenolate (1) starting from Ge[N(SiMe3)2]2and the corresponding salicyl alcohol is reported. Compound1undergoes an intramolecular oxidative insertion reaction of germanium into a C–O bond to result in a cyclic germanium(IV) tetraoxidogermocane (2). Addition of 3‐tert‐butyl‐2‐hydroxy‐5‐methylbenzyl alcohol to either compound1or2gave a spirocyclic monoorgano dioxagermine (3). The results of1H NMR spectroscopic studies and DFT‐D calculations are in agreement with the proposed reaction cascade in which the novel germylene1is first converted into the germocane2followed by reaction with 3‐tert‐butyl‐2‐hydroxy‐5‐methylbenzyl alcohol to finally provide compound3. Addition of 4‐(dimethylamino)pyridine to a solution of germylene1resulted in the formation of an air‐stable monomeric 1:1 complex (4). The characterization of compounds1–4by single‐crystal X‐ray diffraction analysis, thermal analysis, and1H NMR,13C{1H} NMR, and ATR‐FTIR spectroscopy is presented.
