Visão geral

BIBB is an important reagent in the synthesis of amides, macrocyclic amides, ketenes, and alkynic ketones.


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.
