Allgemeine Beschreibung

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

Anwendung

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

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

Biodegradable poly(2-hydroxyethyl methacrylate)(pHEMA) hydrogels for engineered tissue constructs were developed by the use of atom transfer radical polymerization (ATRP), a degradable cross-linker, and a macroinitiator. Hydrogels are appropriate materials for tissue engineering scaffolds because of their tissue-like mechanical compliance and

Reaction of 2-substituted dienamides with catalytic amounts of copper halide/tripyridylamine (TPA) furnishes either 5-exo or 6-endo products with the outcome dependent upon the radical initiating unit. Reaction of 3-substituted dienamides produces beta-lactams via a 4-exo cyclization with termination of the
