Notes:
The separation of the geometric isomers of chromium and rhodium chelates of trifluoroacetylacetone and thenoyltrifluor-oacetone was investigated using packed column supercritical fluid chromatography. Mobile phases consisting of neat and alcohol-modified carbon dioxide were used, and the most favorable isomeric resolution was obtained with a phenyl stationary phase. The chromatographic performance was better for chelates with trifluoroacetylacetone than for the corresponding chelates with thenoyltrifluoroacetone. Chromatographic peak area analysis of the metal chelates investigated showed appropriate isomeric concentrations in the final diastereomeric products resulting from the synthetic procedures.
