摘要： Compounds or polymers that contain carbon-carbon unsaturation are brominated using a quaternary phosphonium tribromide as the brominating agent. The bromination process proceeds easily under mild conditions. The process can be highly selective. When the substrate is a butadiene polymer or copolymer, the brominated product tends to have excellent thermal stability.
