metal-catalyzed aerobic alcoholoxidation is an attractive method for the synthesis of carbonyl compounds, but most catalytic systems feature precious metals and require pure oxygen. The vanadium complex (HQ)2VV(O)(OiPr) (2 mol %, HQ = 8-quinolinate) and NEt3 (10 mol %) catalyze the oxidation of benzylic, allylic, and propargylic alcohols with air. The catalyst can be easily prepared under air using commercially
过渡金属催化的好氧醇氧化是合成羰基化合物的一种有吸引力的方法,但是大多数催化系统均以贵金属为特征,并且需要纯氧。钒络合物(HQ)2 V V(O)(O i Pr)(2摩尔%,HQ = 8-喹啉酸酯)和NEt 3(10摩尔%)催化苄醇,烯丙基醇和炔丙基醇在空气中的氧化。该催化剂可以使用市售试剂在空气中容易地制备,并且对多种伯醇和仲醇有效。
