Organo-Polygermanes Containing Three or More Germanium Atoms

2 ORGANO-POLYGERMANES CONTAINING THREE OR MORE GERMANIUM ATOMS 

Understanding of the nature or organo-polygermanes as cyclic or chain-type compounds with Ge-Ge bonds has greatly improved, mainly through the continued work of Neumann, et al. and also by Glockling and coworkers. The compounds in Table 7 are prepared by methods from the following scheme. 

II Synthesis with organic derivatives of alkali metals  

By rxn. of MeLi and RLi with GeCU in EtsO, in 8% yield ( +93) By-prod, in rxn. of GeCU with large excess AICI3 in N atm. (IIO8).
