Popis:	The changes in the chemical shifts of organic molecules during complex formation are well known in organometallic chemistry [24]. Thus, coordinated dienes lose the olefinic characteristics; they are not hydrogenated, do not enter into the Diels-Alder reaction, and react with electrophilic reagents. At the present time the search for a link between the structure of organometallic complexes in terms of rigorous quantum-chemical calculations is beginning. The construction of experimentally substantiated models which make it possible to explain qualitatively the marked changes in the characteristics of organic compounds in the presence of the atoms of transition metals is therefore essential for a deeper understanding of the orbital mechanisms lying at the basis of catalysis.
