A group effort: Reported is the title reaction using a polycomponent catalytic system involving commercially available Selectfluor, a putative radical precursor N‐hydroxyphthalimide, an anionic phase‐transfer catalyst (KB(C6F5)4), and a copper(I) bis(imine). The catalyst system formed leads to monofluorinated compounds selectively (see example) without the necessity for an excess of the alkane substrate
共同努力:报告为使用多组分催化体系的标题反应,涉及可商购的Selectfluor,推定的自由基前体N-羟基邻苯二甲酰亚胺,阴离子相转移催化剂(KB(C 6 F 5)4)和铜(I)二(亚胺)。形成的催化剂体系选择性地产生单氟化化合物(参见实施例),而无需过量的烷烃底物。

characterization as well as with DFT-based theoretical calculations of stable dialkyl ether/poly(hydrogenfluoride) complexes are reported. Dimethyl ether/poly(hydrogenfluoride) (DMEPHF), are stable complexes of particular interest and use. The DFT calculations, that are in agreement with NMR data, suggest a cyclic poly(hydrogenfluoride) bridged structure for DMEPHF. The complex, DME-5 HF was found to be a convenient
