Reactions of ligands similar to molecular nitrogen and being capable to take its coordination place in complexes

Reactions of ligands similar relative to molecular nitrogen in complexes of transition metals are djscussed. Isonitriles, carbon monoxide, carbon dioxide, olefins, acetylenes, cyanide, nitrils, nitrogen monoxide, azide are considered as investigated ligands. It is concluded that, as a rule, both for coordination of N2 and its analogs metal complexes rich with electrons and able to stabilize even sUch unstable particles as carbenes or carbynes formed under the effect of electrophilic reagents on coordinated isonitrils are most suitable. Reactions of introduction and oxidation of complexes with N2 analogs are considered
