The reaction pathway for the addition of alkynes to tetramesityldigermene was examined using a cyclopropyl alkyne mechanistic probe. The results obtained indicate that the reaction is stepwise and involves biradical intermediates.

Tetramesityldigermene (1) can be synthesized cleanly and quantitatively by photolysis of hexamesitylcyclotrigermane (2) in THF at low temperature. A solution of tetramesityldigermene (1) in THF is stable for several weeks at room temperature; the digermene does not dissociate or rearrange. The molecular structure of tetramesityldigermene (1) has been determined using X-ray crystallography. The effectiveness of the new protocol for the synthesis of tetramesityldigermene (1) and its derivatives has been demonstrated in the study of the addition of carboxylic acids to tetramesityldigermene (1).

The addition of atmospheric oxygen to tetramesityldigermene under a variety of conditions was studied. The addition of oxygen to the digermene, prepared by the photolysis of hexamesitylcyclotrigermane in THF, cleanly afforded 3,3,4,4-tetramesityl-3,4-digermadioxetane (7). The photolysis of hexamesitylcyclotrigermane in toluene in the presence of triethylsilane under the ambient atmosphere gave a very complex product mixture, from which 2,2,4,4-tetramesityl-2,4-digermadioxetane (9), tetramesityldigermaoxirane (10) and 2,2,4,4,5,5-hexamesityl-2,4,5-trigermadioxolane (11) were isolated and identified. The structures of compounds 9 and 11 were determined by X-ray crystallography.
A Facile Digermene-to-germylgermylene Rearrangement; Bulky Germylene Insertion into the Si-H Bond

The thermolysis of hexamesitylcyclotrigermane 1 in the presence of triethylsilane at 105 deg C yields dimesityl(triethylsilyl)germane 2 and 1,1,1,2-tetramesityl(2-triethylsilyl)digermane 3; the molecular structure of 3 has been determined by X-ray crystallography.
