The methods for the preparation of compounds containing germanium-nitrogen bonds have been the subject of a recent review.140... 

A germanium-nitrogen complex containing two Ge atoms disposed in an acyclic array was obtained via the formation of the intermediate germylene [(Me3Si)2N]GeCl, which was converted into a germanium(iv) adduct via an insertion reaction (Scheme 19).157... 

Dehydrohalogenation reactions appeared to be a convenient route to double bond germanium nitrogen species and were commonly carried out with an organolithium compound as a base.3,4 5b 6 7 96,97 123 Accordingly, the synthesis of two moderately hindered stable germanimines Mes2Ge = NR 136 and 137 has been reported.59 Stabilization in these cases is achieved... 

Reactivity of stable germanium-nitrogen double bond compounds has been widely documented in previous reviews.3,4,6,7,119... 

Optical activity was first observed with organic compounds having one or more chiral carbon atoms (or centres) (i.e. a carbon substituted with four different groups). In the structures (1) to (17) the chiral carbons are specified with an asterisk. Subsequently compounds having chiral centres at suitably substituted heteroatoms (e.g. silicon, germanium, nitrogen, phosphorus, arsenic, sulphur, etc.) were also synthesised. Molecular dissymmetry, and hence chirality, also... 

Comparison of theoretical data with experimental spectra led also to the identification of compounds which have germanium-nitrogen double and triple bonds. Foucat et al. report about the results of flash vacuum thermolysis of substituted germacyclopentenes and DFT (B3LYP) calculations of model compounds of possible reaction products114. The authors took the experimental photoelectron (PE) spectra and compared them with...

Primary Reactimis of Polyvalent Recotling Atoms. We have dwelled thus far on the identification of reactive intermediates in the reactions of polyvalent recoiling atoms. Only in the cases of carbon, silicon, germanium, nitrogen, and phosphorus have complete reaction... 

In principle alkali metal derivatives of germanes can be converted to compounds containing a germanium-nitrogen bond. This synthetic method is of a very limited scope since trialkylgermyl-alkali metal compounds can...

Moreover, while investigating the properties of these compounds some other types of compounds containing a germanium-nitrogen bond were prepared for comparison purposes. In Table IV the compounds synthesized and the methods of preparation employed are summarized.
