Preparation of dipolar Y(III)-based monoporphyrinate complexes: conventional vs microwave-assisted reaction and theoretical IR study
The dissymmetrical and dipolar Y(III) complex 2 and its cationic precursor 1, containing the proligands 5,10,15,20-tetrakis(4-bromophenyl)porphyrin L1 and 1-anisyl-1,3-butanedione L2, were synthesized at fairly high yields, ranging from 40 to 78%, by conventional and microwave-assisted techniques, and were isolated as a microcrystalline compound. The products obtained in each case were characterized by 1H-NMR, mass spectrometry, elemental analysis, Med-IR and Far-IR. The IR information collected shows good agreement with respect to the density functional theory (DFT) calculations carried out, validating the molecular geometry in each case. This innovative one-pot microwave-based method contributes an efficient pathway for obtaining challenging molecular architectures based on monoporphyrinate complexes without Diglyme.
期刊介绍：
The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites.
The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
