- Mild, highly selective brominating agent. Ketones can be ɑ-brominated in the presence of a double bond: the low concentration of enol form consumes the bromine as it is slowly liberated: Can. J. Chem., 47, 706 (1969). Acid sensitive substrates can be brominated with PHT with excess pyrrolidinone: Synthesis, 59 (1990). Bromination with PHT is facilitated by the presence of free radicals or trace peroxides (as in THF or dioxane). In DMSO, dehydrobromination may occur: J. Org. Chem., 55, 6161 (1990):
