Chemical Properties:

  1. Colorless or slightly yellow liquid
  2. 2-Bromoisobutyryl bromide is an organic compound with a molecular formula of C4H6Br2O and a molecular weight of 229.91. The molecule contains an acyl group and two bromines. It is a yellowish transparent fuming liquid at room temperature. The chemical properties are relatively active, and it can undergo nucleophilic substitution reactions with nucleophiles, and is widely used in organic synthesis.
  3. Bromine was added dropwise to the mixture of isobutyric acid and red phosphorus, reacted at 100° C. for 6 hours, and unreacted bromine and hydrogen bromide were evaporated under reduced pressure. After cooling, the phosphorous acid is separated to obtain the crude product of 2-bromoisobutyryl bromide. The crude product is fractionated under reduced pressure, and the 91-98°C (13.3kPa) fraction is collected, which is the finished product.

Application:

  1. In the field of polymer polymerization, 2-bromoisobutyryl bromide is often used for the synthesis of macromolecular initiators. One of the bromine atoms is used to replace the grafting reaction, and the other bromine atom can be used as the active center to initiate atom transfer radical polymerization (ATRP). It should be noted that the reaction activity of 2-bromoisobutyryl bromide is very high and generally requires an ice bath (0°C).
  2. Living/controllable free radical polymerization (L/CRP) has the advantages of both free radical polymerization and living polymerization. For example, the monomer has a wide application range, the reaction conditions are easy to control and realize, and it can carry out bulk polymerization, solution polymerization, emulsion polymerization, etc. A polymer with controllable molecular weight and narrow distribution is obtained. Atom transfer radical polymerization (ATRP) is a new type of living free radical polymerization method developed since 1995. Compared with other living free radical polymerization, its outstanding advantages include the need for traditional initiators and suitable monomers. Wide, mild reaction conditions, strong initiator molecular design ability, suitable for the preparation of relatively pure copolymers with multiple topological structures.
