Why is ethanol (vs. water) commonly used as a solvent during chloro(pyridine)cobaloxime(III) synthesis?
Homework Answers
Chloro(pyridine)cobaloxime(III) is also named as Chloro bis ( dimethylglyoximato) ( pyridine) cobalt (III).It is widely used as a catalyst for C-C ,C-O , C-N, C-H bond formation.when ethanol vs water (aqueous ethanol) is used as a solvent for the preparation , this cobaloxime compound has less solubility in this organic solvent such as ethanol.due to their low solubility chloro pyridine cobaloxime (III) and cobaloxime (II) can be easily removed by adsorptive filtration of the reaction mixture in a short silica gel coloum.
