Karpus, Andrii;Harrisson, Simon;Poli, Rinaldo;Mazieres, Stephane;Manoury, Eric;Destarac, Mathias research published 《 Well-Defined PIII-Terminated Polymers from Phosphorylated Carbodithioate RAFT Agents》, the research content is summarized as follows. Five S-alkyl di-tert-butylphosphorylated carbodithioates, Z-C(S)SR, were studied as chain transfer agents (CTAs) in the RAFT polymerization of vinyl monomers. These phosphorus-containing CTAs involve new PIII and PV moieties in the Z group (phosphine-borane or free phosphine). Two of them, with an S-bonded 1-methoxycarbonylethyl group as leaving group, have not previously been described. The CTAs with a PV Z group provide good control over the polymerization of styrene (St) and Bu acrylate (nBA). Molar masses are close to theor. values, and dispersities are consistently low during polymerization The monitoring of polymerization by 31P NMR spectroscopy supports the controlled character and the integrity of the polymer chain ends. Conversely, they inhibit the polymerization of the less-activated monomer vinyl acetate (VAc). The reactivity of the CTAs with a PIII Z group mainly depends on the reaction medium, and their performance for St, nBA, and VAc was surprising and unexpected. Theor. calculations were carried out to rationalize their behavior. Finally, an innovative strategy was developed to obtain well-controlled polymers with free phosphine ω-chain ends.
5445-17-0, Methyl 2-bromopropionate, also known as Methyl 2-bromopropionate, is a useful research compound. Its molecular formula is C4H7BrO2 and its molecular weight is 167 g/mol. The purity is usually 95%.
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., Category: bromides-buliding-blocks
