abstract: The work mainly focuses on amino gallium compounds and their chemistry. First of all, the synthesis and analysis of silylamines and their salts are shown and discussed. Several crystal structures could be obtained.

Lithiated silylamines and their reactions with different gallium sources are the second part of this work. This class of compounds are used as bulky substituents in different disciplines of chemistry. In relation to the current work their reaction with Ga2X4 (X = Cl, I) possibly lead to homoleptic amino digallanes. Novel cage compounds can be obtained by the reaction of these homoleptic digallanes with low valent gallium sources. Their x-ray structures will be discussed as well. Beyond this the focus is on various types of digallanes with a novel heteroleptic digallane and its reactions with carbon dioxide and potassium-tert-butanolate. Crystal structures of Ga(III)-species will be shown afterwards. Those compounds with more than one halide substituent will be treated with reducing agents thus leading to new low valent gallium species.

Amino compounds of Gallium(III) are used in the semiconductor industry which has been developed fast in the last years. It is of great interest to cover the need of high efficient materials through the development of better compounds. As a part of the project ‘development of GaInNAs materials for concentrator solar cells for the photovoltaics’ the goal is to examine new precursor materials for the epitaxy (Chapter 7.5). Based on quantum-chemical calculations a further big goal is the synthesis of the ideal precursor or rather the prediction of possible products of decomposition.
