A mixture of the manganese and cobalt salts of the acid is used to catalyze allylic and benzylic alcohols to their corresponding carbonyl compounds in reasonable yields using oxygen or air. Reactions are clean and the catalysts can be recovered easily and reused repeatedly.  UR - https://ijcce.ac.ir/article_10920.html L1 - https://ijcce.ac.ir/article_10920_4115fbe44ac6d8e733ae4242085faa42.pdf ER -
