*Sarrett's reagent: a solution of CrO<sub>3</sub>(pyridine)<sub>2</sub> in pyridine. It was popularized for selective oxidation of primary and secondary alcohols to carbonyl compounds.<ref>Poos, G. I.; Arth, G. E.; Beyler, R. E.; Sarrett, L. H. ''J. Am. Chem. Soc.'', '''1953''', ''75'', 422.</ref> showed that pyridine reacts with CrO<sub>3</sub> in
*[[Collins reagent]] is a solution of CrO<sub>3</sub>(pyridine)<sub>2</sub> in dichloromethane. The Ratcliffe variant of Collins reagent relates to details of the preparation of this solution, i.e., the addition of chromium trioxide to a solution of pyridine in methylene chloride.
