Surprising insight into a classical mechanism is provided by theoretical and experimental investigations on the bromination of alkynes. in nonpolar solvents the bromination of acetylene via a covalent tribromide adduct is strongly favored over the textbook mechanism via a bridged bromirenium ion. The structurally interesting intermediate explains the syn selectivity of the bromination of strained cycloalkynes.
