Reversed-phase separation of ionic organoborate clusters by high-performance liquid chromatography

Chromatographic separation on reversed-phase materials was carried out for mercaptoundecahydrododecaborate (B 12H 11SH 2-) and derivatives with organic residues attached to the sulfur. Solvent and ion-pair systems are described that allow the separation of compounds with greatly different structures...

Summary:Chromatographic separation on reversed-phase materials was carried out for mercaptoundecahydrododecaborate (B 12H 11SH 2-) and derivatives with organic residues attached to the sulfur. Solvent and ion-pair systems are described that allow the separation of compounds with greatly different structures. Gradient systems of ion-pair reagents with methanol could be used to separate compounds with greatly different degrees of hydrophobicity. A gradient system was developed in which B 12H 11SH 2--substituted porphyrins and other polar and non-polar porphyrins could be separated.
