Condensations of complexed dialkylgermylenes R2Ge · NEt3 with various oxiranes and thiirane gave, by insertion and ring expansion, the corresponding oxa- and thia-germacyclobutanes . 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.
