Applications de la RMN 13C a l'identification des sites d'association dans le cas de systemes polyfonctionnels

Application of 13 C NMR to the identification of association sites for polyfunctional compounds. Auto association of m and p substituted phenols (XC 6H 4OH) has been studied by 13 C NMR. For the various aromatic carbons, the slopes of dilution curves chemical shifts/concentration separate homofunc...

Description
Summary:Application of 13 C NMR to the identification of association sites for polyfunctional compounds. Auto association of m and p substituted phenols (XC 6H 4OH) has been studied by 13 C NMR. For the various aromatic carbons, the slopes of dilution curves chemical shifts/concentration separate homofunctional associationsOH⋯OH and heterofunctional associationsOH⋯X between the OH group and the lone pairs of the X substituents. L'auto association de phénols m et p substitués (XC 6H 4OH) et étudiée par RMN 13C. Pour les différents carbones aromatiques, la pente des courbes de dilution déplacements chimiques/concentration différencie les associations homofonctionnellesOH⋯OH et les associations héterofonctionnelles OH⋯X, entre le groupe OH et les doublets libres des groupes substituants X.
