The new complexes 5-C5H5)(CO)2> (R=Et or Ph) were prepared by a substitution reaction from the corresponding arylhalohydrodigermanes and the iron salt.Their characterization by IR, 1H and 13C NMR and mass spectroscopy is reported.Photolysis of each complex affords transient monohydrogermylcomplexes 5-C5H5)(CO)2> and dialkylgermylenes which are trapped by 3,5-di-tert-butylorthoquinone and dimethyldisulphide with correct yields.These photolytic reactions are not affected by radical initiators like peroxide.
ASSISTANCE NUCLEOPHILE DANS DES REACTIONS D'ORGANO-HALOGENO- ET -HALOGENO-HYDROGERMANES: GERMYLANIONS, GERMYLENES, DERIVES FONCTIONNELS DU GERMANIUM

Substitution reactions of halogermanes under nucleophilic assistance of tertiary amines or diazo derivatives leading readily to various functional derivatives of germanium have been carried out.Dehydrohalogenation of acidic halohydrogemanes under nucleophilic assistance is a useful way to divalent species, and the germylenes formed are stabilized by complexation with the nucleophilic agent.The reactions proceed via intermediate halogermylanions which lead to the formation of more stable germylenes.The transient halogemylanions have been characterized by means of their nuclophilic additions to carbonyl derivatives.Nucleophilic substitutions of halogermanes using these germylanions lead to the formation of polygermanes.
