The administration to rats of cholesta-3:5-dien-7-one.
The fact that cholesta-3:5-dien-7-one occurs in arteriosclerotic aorta and some other tissues, in small amounts (Hardegger, Ruzicka & Tagmann, 1943; Prelog, Ruzicka & Stein, 1943), and that it is not necessarily an artifact (Kantiengar & Morton, 1955a) makes it desirable to study the effect of administering it to animals. In the present work it has been given to rats orally at the rate of 25 mg...

Cyclopropenium ion catalysed Beckmann rearrangement.
1-Chloro-2,3-diphenylcyclopropenium ion was found to be a very efficient organocatalyst (3 mol% loading) for liquid phase Beckmann rearrangement of various ketoximes to the corresponding amides/lactams within 2 h in acetonitrile at reflux temperature. This is the first example of the application of the cyclopropenium ion as a catalyst, which opens up a new aspect of the synthetic utility of aro...
متن کاملOne-pot Efficient Oximation-Beckmann Rearrangement of Ketones Catalyzed by Fe3O4 Under Solvent-free Conditions
Fe3O4 nanoparticles were employment as an efficient and magnetically separable Nano catalyst for the synthesis of amides via one-pot Beckmann rearrangement of ketones under solvent-free conditions. Various secondary amides were synthesized by this method in moderate to good yields. The catalyst showed high thermal stability and was recovered and reused at least five times without any considerab...
