Thermal reactions of a stable germacyclopropabenzene, Tbt(Dip)GeC 6H4 (Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl)phenyl, Dip = 2,6-diisopropylphenyl), with elemental chalcogens in C6D 6 at 130°C resulted in the formation of novel Ge-containing four-membered heterocycles, 2H-benzo[c][1,2]chalcogenagermete derivatives. This is the first example of a ring expansion reaction of cyclopropabenzene derivatives using elemental chalcogen, while several types of ring-opening reactions have been explored for cyclopropabenzene so far. In addition, the 2H-benzo[c] [1,2]telluragermete is the first stable compound as a tellurete derivative. Structures of the chalcogenagermetes obtained here were elucidated by X-ray crystallographic analysis, and the experimentally obtained structural parameters were supported by theoretical calculations. The skeletons of chalcogenagermetes have very little strain in their four-membered rings annelated with a benzene ring.
