Archived from the original on 1 March For example, n -propylbenzene is oxidized to propiophenonebenzyl methyl ketoneand several chlorinated products, with benzyl methyl ketone being the major product. Home Questions Tags Users Unanswered. Oxidation of N-propylbenzene and methylcyclohexane with chromyl chloride”. Post as a guest Name. For example, the first step in the synthesis of ephedrine is condensation of benzaldehyde with nitroethane [ citation needed ].

Jan I am uploading the picture of hydrolysis please check it in the answers column. Other oxidation reagents like potassium permanganate or potassium dichromate oxidize to the more stable carboxylic acids. The reaction is normally carried out for a few days to several weeks and the yields are high. Obtaining specific aldehyde products from reagents other than toluene tends to be difficult due to rearrangements.
