Liedholm, Brita published the artcile< Copper(I) catalyzed replacement of bromine by chloride ion in halonitrobenzenes>, Safety of 2-Bromo-1-chloro-3-nitrobenzene, the main research area is halo nitro benzenes substitution; nitro halo benzenes substitution; substitution halo nitro benzenes; benzenes halo nitro substitution.
The Cu(I) catalysed exchange of Br for Cl in aqueous HCl-AcOH was kinetically studied under homogeneous conditions in 2-bromo-3-chloronitrobenzene, 2,3-dibromonitrobenzene, and other halonitrobenzenes at 80, 90, and 98°. The concentration of the catalyzing Cu(I) complex, CuCl2-, was estimated from the dependence of the first-order rate on Cl- concentration A strong accelerating effect of an o-nitro group was observed The possibility of a transition state in which the o-nitro group participates with CuCl2- and the Br to be replaced in the formation of a tetrahedral Cu(I) complex is discussed and the activation parameters are presented.
Acta Chemica Scandinavica (1947-1973) published new progress about Substitution reaction catalysts. 19128-48-4 belongs to class bromides-buliding-blocks, and the molecular formula is C6H3BrClNO2, Safety of 2-Bromo-1-chloro-3-nitrobenzene.
