Popis:	Aminocarbenechromium complexes of the general structure (CO)5CrC(R)N-(CH2)nXCH2 (n = 0, X  CH2; n = 1, X  CH2; n = 1, X  CHCH; n = 2, X  molecules of alkyne and one molecule of CO, and CN bond cleavage, new polycyclic heterocycles. The reactions of the pyrroline-, the tetrahydropyridine-, the pyrrolidine- and the methylaziridine-substituted complexes are mainly considered, and the results of X-ray structural studies of the new products are presented. The mechanism of the rearrangement of a 1,5 dipole is discussed.
