Polycyclic 3d-metalchelates formed owing to inner-sphere transmutations in the gelatin matrix: synthesis and structures

Abstract

AbstractProcesses of synthesis of polycyclic compounds containing various 3d-elements, proceeding in gelatin matrix in the systems M(II) ion – (N,S)- or (N,O,S)-containing organic compound A – mono- or dicarbonyl-containing organic compound B, resulting in one of a variety of inner-sphere transmutations, namely “self-assembly”, have been considered and discussed. The chemical nature of the final products of such a synthesis formed under these specific conditions have been compared with the chemical nature of the final products formed by similar synthesis in solutions. It has been noted that in many cases, the nature and chemical composition of these products differ substantially. Specific features of the density functional theory calculated molecular structures of the metal macrocyclic compounds that can be formed due to such a synthesis in the systems indicated above have been discussed, too. The review covers the period 1990–2016.
