Hypovalent and Hypervalent Germanium Atom

Compounds having a Hypovalent and Hypervalent Germanium Atom 

In spite of these failures, all the authors had no doubts that diorganylgermylenes were the intermediates in the reactions studied. 

Nefedov and coworkers202 had proven in their first publication that Me2Ge was the intermediate formed in the reaction of Me2GeCl2 and Li, since when the reaction was conducted in the presence of styrene, 1,1-dimethyl-3,4-diphenyl-1-germacyclopentane was formed in 40% yield. 

It was surprising that Neumann did not investigate the thermal and photochemical reactions of the decomposition of (Ph2Ge) . 

Cited as follows, publications of Nefedov and Kolesnikov201-207,507, Neumann175,199 200 508 509 and their coworkers can be regarded as the beginning of the chemistry of diorganylgermylenes.
