Aryl-assisted halogen exchange and rearrangements of 2-bromo-1-chloro-3-arylpropanes and 1-bromo-S-chloro-2-arylpropanes. Evidence for a competitive bromine-assisted pathway in the case of 1,2-dibromo-3-arylpropanes

Ion pairing, ring opening, and the rates of formation of aryl-bridged chlorinated intermediates are investigated through reactions of mixed 1,2-dihalo-3-arylpropanes and 1,3-dihalo-2-arylpropanes (aryl = C6H4X with X = H and X = p-Me) and are compared with previous results for X = p-OMe; this allows an estimation of the free energy difference between isomeric aryl-bridged (3-bromopropylene)benzenium ions and bromine-bridged 3-arylpropylenebromonium ions.
