cis-Bromination of Alkynes without Cationic Intermediates
Angewandte Chemie - International Edition, 2005 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 ...
