activation of the perfluorinated analogue of dimethyl sulfoxide, DMSO-F6, by hydroxyl radicals efficiently produces trifluoromethyl radicals based on pulse radiolysis, laboratory scale experiments, and comparison of rates of reaction for analogous radical systems. In comparison to commercially available precursors, DMSO-F6 proved to be more stable, easier to handle and overall more convenient than leading
基于脉冲辐射分解,实验室规模的实验以及对类似自由基系统的反应速率的比较,羟自由基对二甲基亚砜DMSO-F 6的全氟化类似物的氧化活化可有效产生三氟甲基自由基。与市售前体相比,DMSO-F 6被证明比领先的F 3 C试剂更稳定,更易处理且总体上更方便,因此可能是研究F 3 C自由基进行时间分辨动力学研究的理想替代品。此外,我们提出了一种改进的方案,用于制备这种很大程度上未开发的试剂。
