Description
- General description: BIBB is an important reagent in the synthesis of amides, macrocyclic amides, ketenes, and alkynic ketones.[1]
- Application: α-Bromoisobutyryl bromide has been used:as atom transfer radical polymerization (ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxide[2]to form an N-protected halodienamide which provided four- and five-membered lactams in the presence of copper (I) and a tertiary amine[3]in preparation of polycaprolactone macroinitiator via reaction with oligomeric caprolactone diol[4] and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface[5]
