Liu, Lilian Kao published the artcileReaction of aromatic and unsaturated compounds with the potassium permanganate/HCl (HBr) acetonitrile reagent, Computed Properties of 594-81-0, the publication is Journal of the Chinese Chemical Society (Taipei) (1996), 43(1), 61-6, database is CAplus.
Addition of hydrochloric or hydrobromic acid to a solution of potassium permanganate in acetonitrile produced a homogeneous mixture, which is suitable for laboratory chlorination or bromination, resp. Aromatic compounds more reactive than alkylbenzenes can be chlorinated or brominated without addnl. catalyst. Alkenes and alkynes give the corresponding vicinal dihaloalkanes and vinyl halides. All reactions complete within two hours under mild condition (25-60°) with excellent to moderate yields.
Journal of the Chinese Chemical Society (Taipei) published new progress about 594-81-0. 594-81-0 belongs to bromides-buliding-blocks, auxiliary class Bromide,Aliphatic hydrocarbon chain, name is 2,3-Dibromo-2,3-dimethylbutane, and the molecular formula is C6H12Br2, Computed Properties of 594-81-0.
