CCl4 or NBS, unsaturated or hydroxylated piperidines yield difluoroanalogues in good yields. The ability to perform hydride abstraction on chloroderivatives, and the ability to form bridged bromonium ions from unsaturated substrates seem to completely influence the reaction course. Some aspects of the mechanism were clarified by DFT calculations.
在HF / SbF 5中,在CCl 4或NBS的存在下,不饱和或羟基化的哌啶可产生高产率的二氟类似物。对氯代衍生物进行氢化物提取的能力以及从不饱和底物形成桥连溴离子的能力似乎完全影响了反应过程。通过DFT计算澄清了该机制的某些方面。
