Oxidation of secondary alkanols with the system cerium ammonium nitrate—lithium bromide into ketones, α-bromo ketones, and α,α′-dibromo ketones

Abstract

Oxidation of secondary alkanols with the system Ce(NH4)2(NO3)6—LiBr in aqueous acetonitrile gave ketones, α-bromo ketones, or α,α′-dibromo ketones. The selectivity of the reaction under standard conditions depends only on the molar ratio of the reagents (alkanol: CeIV: LiBr).
