Abstract

Applications of high-performance liquid chromatography in organometallic chemistry: ligand exchange in complexes of ylides. Dimethyl- and di-tert.-butyl-phosphonium-bis-methylide complexes of gold(I) are shown to undergo ligand exchange in methylene chloride solution to form the mixed ligand compound (CH₃)₂P[CH₂AuCH₂]₂P(tert.-C₃H₉)₂. The components of the equilibrium mixture can be identified and separated by analytical and preparative high-performance liquid chromatography, respectively, as well as by high-resolution ³¹P nuclear magnetic resonance spectroscopy. LiChrosorb and LiChroprep Diol phases in combination with ether-methylene chloride eluents at 20°C allowed efficient separations.
