Notizen:
Just as the by now famous Grignard reaction can be used to prepare organomagnesium halides from organic monohalides, organic dihalides can be used under certain conditions to prepare di-Grignard compounds. Difficulties are encountered in particular when the two halide functionalities are separated by only a short carbon chain (i. e. by 1-3 carbon atoms): in such cases side reactions predominate. It has however recently become possible to obtain such “short” di-Grignard compounds on a preparatively useful scale. This opens up new perspectives for the synthesis of metallacyclic compounds of other main group and transition metal elements and in particular for metallacyclobutanes. The preparation, structure and application of a selected number of di-Grignard reagents will be treated in the present review.
