The book discusses one of the independent sections of organoelement chemistry, the development of which is inextricably linked to successes in many practically important areas: polymerization on catalysts of the Ziegler type, application of thin films of metals in radio electronics, chemical fixation of atmospheric nitrogen, etc. The book is written succinctly and clearly. It should be recommended to teachers, graduate students and senior students of chemical universities as an excellent tool for in-depth study of the chemistry of organometallic compounds; it is interesting and useful to all organic chemists working in the field of organometallic compounds.
