Abstract
The ratios of Z- to E-1,2-dibromo-1,2-dihydroacenaphthylene obtained in the bromination of acenaphthylene in chlorinated solvents have been determined by NMR as a function of the reagents concentrations. Kinetic measurements have shown that always the reaction occured through the same rate-determining step. A rationalization involving tight or solvent-separated ion pairs intermediates, is proposed.
