The perfluoro acid esters of N-hydroxypyridine 2-thione give perfluoroalkyl radicals on irradiation. Without any trap the radicals participate in a decarboxylative rearrangement to give 2-perfluoroalkylthiopyridines in excellent yield. In the presence of an appropriate trap, such as an electron rich olefin, adducts are formed in variable yield.

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。
