Two electrophilic monofluoromethylating reagents, monofluoromethyl(phenyl)sulfonium bis(carbomethoxy)methylide (3 a) and monofluoromethyl(4‐nitrophenyl)sulfonium bis(carbomethoxy)methylide (3 b), and their reactions under mild conditions with a variety of nucleophiles, such as alcohols and malonate derivatives, sulfonic and carboxylic acids, phenols, amides, and N heteroarenes, are described. Mechanistic studies with deuterated reagents [D2]3 a/[D2]3 b suggest that these monofluoromethylation reactions proceed through an electrophilic substitution pathway.

单氟甲基取代的Y盐:具有广泛底物范围的亲电单氟甲基化试剂

两种亲电单氟甲基化试剂,单氟甲基(苯基)ulf双(羰甲氧基)甲基化物(3a)和单氟甲基(4-硝基苯基)ulf双(羰甲氧基)甲基化物(3b),以及它们在温和条件下与各种亲核试剂的反应作为醇和丙二酸酯的衍生物,描述了磺酸和羧酸,酚,酰胺和N杂芳烃。用氘化试剂[D 2 ] 3 a / [D 2 ] 3 b进行的机理研究表明,这些单氟甲基化反应是通过亲电取代途径进行的。
