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

A magnetic adsorbent grafted with pendant naphthyl polymer brush for enrichment of the nonsteroidal anti-inflammatory drugs indomethacin and diclofenac.

Ya'nan Deng et al.

Mikrochimica acta, 185(8), 370-370 (2018-07-11)

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

Sikai Chen et al.

International journal of biological macromolecules, 153, 364-372 (2020-02-29)

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

Regiochemistry of copper(I)-mediated cyclization reactions of halo-dienamides.

Andrew J Clark et al.

The Journal of organic chemistry, 72(15), 5923-5926 (2007-07-03)

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

Degradable poly(2-hydroxyethyl methacrylate)-co-polycaprolactone hydrogels for tissue engineering scaffolds.

Sarah Atzet et al.

Biomacromolecules, 9(12), 3370-3377 (2008-12-09)

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
