Abstract

The 2‐quinoxalinol salen copper(II) complex is an efficient catalyst when used with tert‐butyl hydroperoxide for the oxidation of propargylic alcohols to yield the corresponding carbonyl compounds. This catalytic system provides excellent selectivity for the reaction with propargylic alcohols, and high yields (up to 99 %) are achieved within 1 h and with 1 mol‐% of catalyst loading.
