Abstract

For the first time, photochemical properties of compounds 1‐4 containing a cymantrene fragment at the 2‐ or 3‐position of quinazolinone were studied. It was found that the ‐NC=O group in compounds 1 and 2 is capable of coordinating to the Mn atom with the formation of intramolecular chelates. The influence of the nature of a solvent and a substituent in the side chain of cymantrene on the thermodynamic and kinetic stability of dicarbonyl complexes was studied. For the first time, the olefin chelate 9 was isolated; its structure was established by an X‐ray analysis; photochemical and fluorescence properties were studied. Photolysis of compound 4 gives only stable dicarbonyl solvates, in which a solvent can be easily replaced with n‐ and ‐donor ligands.
