摘要:尽管在脂族脱羧方面取得了重大进展,但是自由基芳族脱羧的有效且通用的方案已经远远落后.本文中,我们描述了通过相应的羧酸酯的光敏脱羧,随后在分散的碳-杂原子和碳-碳键形成反应中连续使用的方法,快速访问芳基和烷基的通用策略.识别合适的羧酸活化剂是绕开竞争的单电子转移机制并"开启"能量转移介导的不对称σ键均质裂解的关键,以促进一致的裂解/脱羧过程.

摘要:A chemical synthesis process is provided for the functionalization of monodispersed triblock copolymer (POEw-POPy-POEw) with secondary or tertiary amines at a semi-industrial level in glass reactors having a capacity between 1 L and 100 L. The process includes two stages where the first stage uses an alkylsulfonyl or arylsulfonyl chloride to obtain better leaving groups, and the second stage is the nucleophilic substitution with secondary or tertiary amines, to obtain the bifunctionalized triblock copolymers. The main advantage for this process is to reduce the quantity of unitary process done in each stage, the optimization of reaction times, and the stoichiometric relationships.
