Description:
The main work of this thesis focuses on the elucidation of the aggregation of 2-thienyllithium, methyl-substituted 2-thienyllithium and 2-furyllithium in the solid state and in solution. The addition of an adequate donor base to lithium organics reduces their aggregation. Their solid-state structures is determined by single crystal X-ray diffraction experiments and their coordination behaviour in solution by means of multi nuclear NMR techniques. For many lithium organics the deaggregation proceeded by going from oligomers to monomers, via hexamers, tetramers and dimers. The investigations ...
