Condensations of complexed dialkylgemylenes R2Ge*NEt3 with various oxiranes and thiirane gave, by insertion and ring expansion, the corresponding oxa- and thia-germacyclobutanes (X=O, S).These thermally unstable heterocycles led via β-eliminations to transient dialkylgermanones and germathiones which, by insertion into oxirane and thiirane (excess) formed germadioxolanes and germadithiolanes.Dialkylgermylenes did not react with N-substituted aziridine.Dichlorogermylene reacted with aziridine under formation of aziridinogermylene, while it formed complexes with N-ethylaziridine.Cleavages of aminogermylenes and insertion reactions of complexed dichlorogermylene are described.Dialkylgermylenes insert into the O-H of methanol leading to dialkylmethoxygermanes R2Ge(H)OMe.
