一般描述

BIBB是合成酰胺、大环酰胺、烯酮和炔酮的重要试剂。

应用

α-溴异丁酰溴已用于：
  • 作为原子转移自由基聚合（ATRP）引发剂，用于氧化石墨烯表面上羟基的官能化
  • 形成一个 N保护的卤代二烯酰胺，在铜（I）和叔胺存在下提供四元和五元内酰胺
  • 通过与低聚己内酯二醇反应制备聚己内酯大分子引发剂 通过与固定在外表面的ATRP引发剂反应制备介孔二氧化硅纳米粒子

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

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
