Description 2-Bromoisobutyryl bromide is a bromide that can be used in the chemical industry. It is used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, dyes and other organic chemicals.
Can be used as an atom transfer radical polymerization (ATRP) initiator to functionalize the hydroxyl groups on the surface of graphene oxide;
Formation of N-protected halodienamides in the presence of copper(I) and tertiary amines, which afford quaternary and penta-lactams;
Preparation of polycaprolactone macroinitiators by reacting with oligocaprolactone bis and mesoporous silica nanoparticles;

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
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
