摘要

The structure-reactivity relationship is an importantfeature of organolithium compounds.The knowledge of the structure of reactive species is crucial for the elucidation of reaction mechanisms and the understanding of observed selectivities. This concept article gives an overview over the structural principles of lithium organics and their Lewis base coordinated complexesin the solid state.The transition from the oligomericparent structures to smaller adducts, such asdimers and monomers,as well as special degrees of aggregation is presented.Besides the commonly used alkyllithium compounds,a short overview over the structural principles of the higher homologous silyllithiumcompounds is given. Moreover,the structure-reactivity relationship is depicted by means of the reactivity of the Lewis bases towards intramolecular decomposition reactions with the organolithium compound. Selected examplesconfirm the importance of structure elucidation for the understanding of mechanistic pathways and selectivities.
