By pentaerythritol and α- bromo isobutyryl bromide initiator to initiate the synthesis of star-shaped styrene (St), butyl methacrylate (BMA), and methacryloxy propyl trimethoxy silane (KH-570) reaction of the star macromolecular coupling agent. 本发明的大分子偶联剂结构明确,分子量可控,这使其汇集...
2‑Bromoisobutyryl bromide (BrBiB), 1, 3‑propanesultone, 1‑chloro‑3‑dimethylaminopropane hydrochloride (CDMAP·HCl) (99%), insulin, 4‑vinylphenylboronic acid (VPBA) and pyrene were purchased from Aladdin Chemistry Co., Ltd. Cu powder was purchased from Tianjin Guangfu fine ...
To prepare fluoropolymers usingβ-CD as a core via ATRP, it is crucial to introduce alkyl halides intoβ-CD, and the corresponding detailed synthetic scheme is shown in Fig.1a. In this work, a tailor-made multifunctional macroinitiator, heptakis [2,3,6-tri-O-(2-bromo-2-methylpropionyl]-...
(2) Then, 2-bromoisobutyryl bromide (7.7 mL) was added dropwise under stirring. The reaction mixture was stirred for 12 h in an ice-water bath. (3) The solution after the reaction was recrystallized by isopropanol for several times until the solid turned white. (4) Then, the ...
The resulting monohydroxyl-terminated CPLA was subsequently converted to a bromine-ended macroinitiator (CPLA-Br) by esterification with 2-bromoisobutyryl bromide. Amphiphilic block-brush copolymers with different lengths of hydrophilic block (CPLA-b-P(PEGMA)(4) and CPLA-b-P(PEGMA)(12)) were ...

After 5 min of stirring, ethylene oxide (3.0 g, 50 mmol) and α-bromoisobutyryl bromide (5.0 mL, 15.6 mmol) were sequentially added. The result was precipitated in methanol and vacuum-dried at 40 °C (Mn,GPC = 11,500 g/mol, Mn,NMR = 6700 g/mol, PDI (Polydispersity index) = ...
Lysine amino groups can be smoothly modified with 2-bromoisobutyryl bromide. The installation of a precise number of initiating sites at the protein is the crucial step in the formation of polymer–protein conjugates with a well-defined number of attached polymer chains. Differences in reactivity ...
合成路线图解说明: 2-Aminobenzonitrile (XV) was acylated with 2-bromoisobutyryl bromide (XVI) to afford the cyano amide (XVII). Halogen-metal exchange with ethylmagnesium bromide followed by intramolecular addition to the cyano group of (XVII) gave rise to the quinoline dione (XVIII). This was...
