Germanium hydride derivatives

Thermal instability and lack of convenient preparative procedures have hindered studies of derivatives of the germanium hydrides. However, a great deal of progress has been made, and some very interesting studies on the physical and structural properties of the compounds have appeared in the literature. Preparative details have remained rather sketchy, and the main goal of this chapter is to provide specific instructions for the synthesis of certain represen-... 

Besides the simple alkyl and aryl germanium hydrides, halides, and related derivatives, there are many organogermanium compounds which have organofunctionality of one or more types ... 

Germenes and germaphosphenes can be reduced with lithium aluminum hydride to give the corresponding germanes. This reaction apparently has not been examined for other unsaturated germanium derivatives. 

In a study designed to test the feasibility of a germanium aza Brook rearrangement, the /V-benzyl derivative 25 of amine 24 was treated with BuLi13. After subsequent addition of water, the hydride 28 was obtained as the sole Ge-containing product (Scheme 11). 

These derivatives are useful because of the ability of group IV metals to give anions and especially of germanium which yields optically active germyllithiums from the corresponding hydrides with complete retention of configuration. ... 

Carbon is, of course, unique in the number of hydrides it forms, but the elements in the proximity of carbon in the Periodic Table have a similar, if more restricted, propensity to form hydrides. Silicon, germanium, boron and phosphorus are obvious examples. For hydrides of these elements, and especially for their organic derivatives, the methods of substitutive nomenclature can be applied to obtain suitable names.
