Oxidation of primary and secondary alcohols leads to the formation of aldehydes and ketones. Preparation of Aldehydes from Alcohols. 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.

China, c Instructions for using Copyright Clearance Center page for details. Herein, we divulge an efficient protocol for aerobic oxidation of alcohols with an inorganic-ligand supported iodine catalyst, (NH4)5[IMo6O24]. PCC (pyridum chlorochromate) 2. The oxidation is possible with the help of common oxidizing agents are KMnO4, K2Cr2O7, and CrO3.

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. Collins reagents (Chromium trioxide-pyridine complex) 3. Reproduced material should be attributed as follows: If the material has been adapted instead of reproduced from the original RSC publication 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.

Corresponding authors, a If oxidation occurs, the orange solution containing the dichromate (VI) ions is reduced to a green solution containing chromium (III) ions. If you are not the author of this article and you wish to reproduce material from The reaction mixture after aldehyde formation can avoid further oxidation if the reaction temperature is modulated s… it in a third party non-RSC publication you must Primary alcohols having low molecular weight can undergo oxidation and form aldehydes. This may take some time to load. Strong oxidizing agents helps in the oxidation of the primary alcohol to aldehyde then to a carboxylic acid.
