Silica gel catalyzed α-bromination of ketones using N-bromosuccinimide: An easy and rapid method

An easy and rapid method for the α-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.

In situ-generated zinc bromide-catalyzed α-bromination of alkanones in water

α-Bromination of alkanones with bromine catalyzed by in situ-generated zinc bromide from zinc dust and bromine in water is investigated. Bromination with dioxane-dibromide as a source of bromine does not require zinc dust and provides selectively α-mono and α,α-dibromo products in excellent yields when water is used as solvent.

SELECTIVE MONOBROMINATION OF KETONES BY BIS(DIMETHYLACETAMIDE)HYDROGEN TRIBROMIDE

A unified procedure for the α-monobromination of ketones by bis(dimethylacetamide)hydrogen tribromide in methanol is proposed.Methyl aryl ketones with donating and moderately accepting substituents in the ring readily enter into the reaction. 1-Bromo ketones are mostly formed during the bromination of methyl alkyl ketones.

Oxybromination Catalysed by the Heteropolyanion Compound H5PMo10V2O40 in an Organic Medium: Selective para-Bromination of Phenol

Selective bromination of phenol and its derivatives and the bromination of ketones and alkenes have been achieved by oxybromination at ambient conditions catalysed by the mixed addenda heteropolyanion compound H5PMo10V2O40, which is dissolved in a nonpolar chlorohydrocarbon solvent by complexation with tetraglyme.
