摘要

Abstract The copper (II) complex of 2-quinoxalinol salen (salqu) is an efficient catalyst for the selective oxidation of propargylic alcohols to yield the corresponding α, β-acetylenic carbonyl compounds when used in combination with the oxidant tert-butyl hydroperoxide (TBHP). Excellent yields (up to 99%) are achieved for a variety of propargylic alcohols within 1 h of reaction time. The (salqu) copper (II) complex with TBHP can be used with ...
