Chemical compound
Collins reagent is the complex of chromium(VI) oxide with pyridine in dichloromethane.[2] This metal-pyridine complex, a red solid, is used to oxidize primary alcohols to the corresponding aldehydes and secondary alcohols to the corresponding ketones.
This complex is a hygroscopic orange solid.[1]
