Fan, Bo;Wan, Jing;McKay, Alasdair;Qu, Zhenyuan;Thang, San H. research published ã?Facile synthesis of well-controlled poly(1-vinyl imidazole) by the RAFT processã? the research content is summarized as follows. Poly(vinyl imidazole)s, which contain heterocyclic aromatic rings on the polymer side chains, are of increasing interest for a wide variety of applications ranging from catalysis, polymeric ionic liquids to membrane material. However, the controlled radical polymerization of vinyl imidazoles, including 1-vinyl imidazole (1VIM), 2-vinyl imidazole (2VIM) and 4-vinyl imidazole (4VIM), proved to be extremely challenging in the past decades. Here, we demonstrate, for the first time, that well-controlled and low dispersity (D as low as 1.05) poly(1VIM) could be synthesized via RAFT polymerization by using acetic acid as a special solvent. Acetic acid not only works as a solvent that allows homogeneous polymerization, it also protonates 1VIM, thereby, allowing the stabilization of propagating radicals during polymerization To verify the efficacy of the RAFT polymerization of 1VIM in acetic acid, various polymerization parameters including different RAFT agents, initiator and monomer concentrations, temperatures, etc. had been examined Moreover, detailed kinetic studies revealed a linear, pseudo-first-order polymerization behavior of 1VIM in acetic acid, and the apparent rate constants were calculated Furthermore, the living characteristic of this RAFT process was demonstrated by chain extension with Bu acrylate (nBA) and N,N-di-Me acrylamide (DMA) to form resp. block copolymers with low dispersities. Overall, the synthesis of well-controlled poly(1VIM) is expected to greatly expand the design and utility of vinyl imidazole-based materials and their applications in catalysis, membrane material, heavy metal removal, fuel cells and many other fields.

Methyl 2-bromopropionate is used in the synthesis of poly(ADP-Ribose)polymerase inhibitors derived from benzoxazin-3-one. Also used in the synthesis of 5-HT2C antagonists affecting serotonin levels.
Methyl 2-bromopropanoate is a chemical compound that can be synthesized in an asymmetric manner. The reaction of methyl 2-bromopropanoate with hydrochloric acid gives the corresponding carboxylic acid, methyl propanoate, and hydrogen bromide in a 1:1 ratio. It has been shown that methyl 2-bromopropanoate is a potential catalyst for the reduction of chloride to chloride ion via the borohydride reduction method. Methyl 2-bromopropanoate has also been used as a model system for studying halides and copper complexes. Magnetic resonance spectroscopy studies have revealed that this chemical compound has a high redox potential and kinetic properties., 5445-17-0.
