The electrochemical bromination of benzene, toluene and p-xylene has been investigated in acetonitrile; even if the mechanism was found to be somewhat similar to that postulated in a previous paper for acetic acid as the solvent, the yields of the brominated products in this case are near to ...

Scheme 1.Preparation of clenbuterol from 4-amino-3,5-dichloroacetophenone. Clenbuterol has also been synthesized fromp-aminoacetophenone through benzene ring chlorination using polymer Lewis acid PVC–FeCl3as catalyst, α-hydrogen brominating using CuBr2as brominating agent, amination with H2NCMe3, ...
Benzylic oxidation –complete oxidation of an alkyl group adjacent to benzene to a carboxylic acid. 3. “Phenyl” vs “Benzyl” : What’s The Difference? First, one quick order of business. Let’s get some important nomenclature out of the way, because “phenyl” and “benzyl” cau...
The product distribution from the bromination of resorcin ( m-dihydroxybenzene) is influenced by mixing in an experimentally convenient range of concentration and mixing intensity at room temperature. The degree of bromination is insensi... JR Bourne,P Rys,K Suter - 《Chemical Engineering Science》...
of adjacent, but unsubstituted, positions. Thus more drastic and stringent reaction conditions are necessary to effect further introduction of bromine into the ring. For example, in the prior art, to prepare hexabromobenzene from benzene, mono-, or dibromobenzene the bromination is conducted in ...
Palladium-catalyzed allylic C–H amination of alkenes with N-fluorodibenzenesulfonimide: water plays an important role A new palladium-catalyzed highly regioselective allylic C–H amination of alkenes with NFSI in the presence of a catalytic amount of water was developed an... T Xiong,Y Li,L ...
