The present communication describes catalytic bromination of alkanes (decane and dodecane), cyclo- alkanes (cyclohexane and adamantane), haloalkanes (butyl chloride) and arylalkanes (toluene, p- and m-xylenes, and mesitylene) by the action of CBr4 in the presence of metal-complex catalyst. The process follows the equation ... This reaction can be regarded as metathesis of CÄH and CÄBr bonds in saturated compounds. Reaction (1) in the ...
