KF-Silica as a stationary phase for the chromatographic removal of tin residues from organic compounds.
Through the simple expedient of using a mixture of KF and silica as the stationary phase in column chromatography, levels of organotin impurities from tributyltin hydride mediated reductions have been reduced from stoichiometric levels to approximately 30 ppm.
