Is pyridinium bromide perbromide a source of bromine or an oxidizing agent in prepration of Meso-Stilbene Dibromide?

Answer 1

yes

Answer 2

Pyridinium bromide perbromide acts as an oxidizing agent in the preparation of meso-stilbene dibromide. It facilitates the bromination of the starting material (stilbene) by generating bromonium ions, which then attack the aromatic ring to form the dibromide product. It is not a direct source of bromine; rather, it helps in the bromination process by generating electrophilic bromine species.
