Description and Uses
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
- to form an N-protected halodienamide which provided four- and five-membered lactams in the presence of copper (I) and a tertiary amine
- in preparation of polycaprolactone macroinitiator via reaction with oligomeric caprolactone diol and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface
