We have already studied in alcohols and phenols that oxidation of alcoholsconverts1° and 2° alcohols to aldehydes and ketones respectively when any one of the following is used : 1. E-mail: The oxidation is possible with the help of common oxidizing agents are KMnO4, K2Cr2O7, and CrO3. Primary alcohols having low molecular weight can undergo oxidation and form aldehydes. scihanyu@163.com, yonggewei@mail.tsinghua.edu.cn, Hansheng654321@sina.com, b contained in this article in third party publications of the whole article in a thesis or dissertation.

Authors contributing to RSC publications (journal articles, books or book chapters) If you are the author of this article you do not need to formally request permission If oxidation occurs, the orange solution containing the dichromate (VI) ions is reduced to a green solution containing chromium (III) ions. or in a thesis or dissertation provided that the correct acknowledgement is given it in a third party non-RSC publication you must [Image will be Uploaded Soon] Aldehydes can also be prepared by the oxidation of primary alcohols or by some other reagents such … The catalyst system is compatible with a wide range of groups and exhibits high selectivity, and shows excellent stability and reusability, thus serving as a potentially greener alternative to the classical transformations. KMnO 4, CrO 3, and K 2 Cr 2 O 7 are some of the oxidizing agents which help in the oxidation of primary and secondary alcohols.

Herein, we divulge an efficient protocol for aerobic oxidation of alcohols with an inorganic-ligand supported iodine catalyst, (NH4)5[IMo6O24]. Highly practical and efficient preparation of aldehydes and ketones from aerobic oxidation of alcohols with an inorganic-ligand supported iodine catalyst† Mengqi Zhang , ‡ a Yongyan Zhai , ‡ a Shi Ru , ‡ a Dejin Zang , b Sheng Han , * a Han Yu * ab and Yongge Wei * bc This may take some time to load. The oxidizing agent used in these reactions is normally a solution of sodium or potassium dichromate (VI) acidified with dilute sulfuric acid. The reaction mixture after aldehyde formation can avoid further oxidation if the reaction temperature is modulated s…
