A catalytic chlorination of ketones was performed by using a vanadium catalyst in the presence of Bu4NI and AlCl3 under atmospheric molecular oxygen. This catalytic chlorination could be applied to the chlorination of alkenes to give the corresponding vic-dichlorides. AlCl3 was found to serve as both a Lewis acid and a chloride source to induce the facile chlorination. A combination of Bu4NI and AlI3 in the presence of a vanadium catalyst under atmospheric molecular oxygen induced the iodination of ketones.
在大气分子氧存在下，使用钒催化剂、四丁基碘化铵（Bu4NI）和氯化铝（AlCl3）对酮进行催化氯化反应。该催化氯化反应可应用于烯烃的氯化反应，以得到相应的邻二氯化合物。发现AlCl3既充当路易斯酸又作为氯源来引发容易的氯化反应。在大气分子氧存在下，四丁基碘化铵（Bu4NI）和碘化铝（AlI3）与钒催化剂组合可引发酮的碘化反应。
