Abstract
A simple, novel, and highly regioselective cleavage of epoxides into vicinal halo alcohols and symmetrical or unsymmetrical dihalides is described using different stoichiometries of triphenylphosphine (PPh3) and N-halo succinimide (NXS) or N-halo saccharine (NXSac). Key words: N-halo succinimide (NXS), N-halo saccharine (NXSac), triphenylphosphine (PPh3), epoxide, vic-halo alcohol, symmetrical dihalide, unsymmetrical dihalide.
