General description

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

Poly(2-naphthyl acrylate) was first grafted onto silica-coated magnetic nanoparticles by surface-initiated atom transfer radical polymerization to prepare a reversed-phase magnetic adsorbent. The resulting polymer brush displays enhanced extraction efficiency by offering active sites on the surfaces of adsorbent. It was

Poultry chicken feather keratin was extracted and then modified for the fabrication of keratin-graft-PNIPAM copolymers. The keratin was well extracted from feather fiber and powdered. Subsequently, it underwent the surficial functionalization process with initiator groups. After the study conducted full
