Re-Butyl bromide

Halogen compounds. re-Butyl bromide Chlorobenzene AUyl bromide Benzoyl chloride. 

The fact that n-butyl benzene can be prepared in reasonable yield by the action of sodium upon a mixture of bromobenzene and re-butyl bromide can be partly explained on the assumption that re-butyl bromide reacts with phenjd-sodium more rapidly than does bromobenzene. It is interesting to note that re-butylbenzene can be prepared either from benz.vlsodium and re-propyl bromide or from phenylsodium and re-butyl bromide (Section VI,29). 

It has been shown that ionic liquids in combination with high temperatures and prolonged reaction times are mandatory in the rrickel catalyzed Heck coupling of aryl bromides and butyl vinyl ether. See Sun L, Pei W, Shen C (2006) J Chem Res 388. For palladium catalyzed Heck reaction of aryl bromides in ionic liquids with added halides. See ref [51]...
