Lewis base-catalyzed perfluoroalkylation of carbonyl compounds and aldimines with (perfluoroalkyl)trimethylsilanes (TMSCF3, TMSC2F5, and TMSC3F7) is described. The nitrogen- or oxygen-containing an...

trifluoromethylation, the perfluoroalkyl anion reagents created by mixing C2F5I and n-C4F9I with tetrakis(dimethylamino)ethylene (TDAE) were effective in their nucleophilic reactions with aldehydes, ketones, imines, disulfides, and diselenides. Irradiation proved beneficial in the aldehyde and ketone reactions.
使用类似于为亲核三氟甲基化开发的方法,通过将C 2 F 5 I和n -C 4 F 9 I与四(二甲基氨基)乙烯(TDAE)混合而产生的全氟烷基阴离子试剂在与醛,酮的亲核反应中有效,亚胺,二硫化物和二硒化物。辐射被证明对醛和酮反应有利。
