Products from bromination of 2-butanone in an aqueous acetate buffer were studied in order to compare the regiochemistry of monobromination with that of deuterium exchange. The good agreement found...
An easy and rapid method for the alpha-bromination of ketones using N-bromosuccinimide (NBS) catalyzed by silica gel in methanol under reflux conditions was developed. The expected products were formed in excellent isolated yields within a short period of time (5-20 min). Major advantages of the present procedure include use of inexpensive and readily available catalyst, exclusion of pre- and post-chemical treatment of catalyst and use of methanol as solvent instead of ethers and chlorinated solvents.
