Applications

2-Bromoisobutyryl bromide is used to prepare N-protected halodienamide, which provides four- and five-membered lactams in the presence of copper(I) and a tertiary amine. Further, it is used as atom transfer radical polymerization(ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxide. It is also used in preparation of polycaprolactone macroinitiators through reaction with oligomeric caprolactone diol and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface.

Notes

Moisture sensitive. Incompatible with strong oxidizing agents and strong alkalis.
