Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 415918-91-1, is researched, SMILESS is C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7, Molecular C36H30NO2PJournal, Article, Angewandte Chemie, International Edition called The Supramolecular Balance for Transition-Metal Complexes: Assessment of Noncovalent Interactions in Phosphoramidite Palladium Complexes, Author is Hartmann, Evelyn; Gschwind, Ruth M., the main research direction is noncovalent interaction palladium phosphoramidite NMR.SDS of cas: 415918-91-1.
The authors have presented a method to determine exptl. and quant. the contribution of noncovalent interactions within transition-metal complexes. In this general approach the ΔΔG value of two complex equilibrium is used as a measure for the deviating noncovalent interactions within the two hetero-complexes. The two equilibrium are energetically linked by the combination of one enantiopure ligand with two enantiomeric ligands, leading to identical or enantiomeric homo-complexes. This allows for the separation of supramol. interactions from stereoelectronic and electrostatic properties provided that the general complex structure is retained. Since this method uses deviating intra-complex interactions within two hetero-complexes, solvation effects of the interacting functional groups are of minor importance. The applicability of this approach was proven with phosphoramidite palladium complexes. The mutual exchange of the CH3 and the Ph groups from one ligand to its enantiomer is directly reflected in the NMR data. The exptl. determined ΔΔG value is of the right order of magnitude for the observed changes in the interaction pattern. This example proves for the first time that the catalytically highly important class of phosphoramidite ligands show a pseudo-bidentate character in solution and that modulations in the extended planar CH-π and π-π interaction interfaces cause significant energetic differences.
