Photolysis of carboxamides with aminomethyl-, 1-aminoethyl-, and aminobenzylcymantrenes led to six-membered dicarbonyl chelates with the Mn - O bond, which are stable in solutions. In the presence of carbon monoxide, the chelates undergo a dark reverse reaction with the formation of the starting tricarbonyl complexes. It was found that the rate determining step of the thermal reaction of the chelates with CO was the chelate ring opening according to the S N1 mechanism of ligand substitution.

The orientation in the metalation of monosubstituted carbamate-, amide-, ureido-, and allyl-containing derivatives of cymantrene was determined for the first time. The data obtained open up a synthetic route to polyfunctional 1,2- and 1,3-disubstituted cymantrenes. They can serve as the starting materials for the preparation of chelate complexes of (dicarbonyl)-(cyclopentadienyl) manganese, which hold promise as novel organometallic photochromes. A method for the synthesis of earlier unknown chiral derivatives of cymantrene with a quaternary carbon atom in position 1 of the side chain was proposed.
