Reactions of N-alkyl- or N-aryl(perfluoroalkyl)thiocarboxamides with alkyl lithium reagents are described. Trifluorothioacetamides are converted into the corresponding lithium salts. Compounds bearing a long polyfluorinated chain terminated by a CHF2 group and compounds containing an N-alkyl substituent with a proton adjacent to nitrogen react further via a multi-step reaction sequence involving HF
描述了N-烷基-或N-芳基(全氟烷基)硫代羧酰胺与烷基锂试剂的反应。将三氟硫代乙酰胺转化为相应的锂盐。带有通过CHF 2基团终止的多氟长链的化合物和含有N-烷基取代基且质子与氮相邻的化合物进一步通过涉及HF消除,然后进行乙烯基氟取代和/或S N '型的多步反应序列进一步反应氟取代。这些转变导致不饱和的N-单取代的多氟代硫代酰胺。

Reaction of direct electrophilic perfluoroacylation of diffferent structure alkenes with trifluoroacetic anhydride activated by BF3.SMe(2) complex leads to trifluoromethylalkenylketones with different structure of alkenyl group. Possible composition of the reactive species is considered on the basis of IR and NMR data. Dependence of the reaction course on the substrate structure is discussed.
