General description

Tetrabromomethane can serve as a mediator, catalyst, and reagent in the synthesis of valuable chemicals.

Application

Tetrabromomethane may be used in the following applications:
  • As a transfer agent for the copolymerization of methylmethacrylate and p-divinylbenzene to form soluble crosslinked polymers.
  • As a catalyst for the aerobic photooxidative synthesis of aromatic esters from benzyl alcohols under metal-free conditions.
  • Bromination of adamantane and its derivatives in the presence of iron compounds as catalyst.
