A new industrial and economical route to trifluoromethyl aryl sufides by thermal decarboxylation of trifluoroacetate salts has been recently developed. The possibility of generalising this reaction of “trifluorodecarboxylation” to RfCO2K (Rf: CCl3, CF2Cl, CF3CF2, CF3CF2CF2) in order to synthesise RfSAr has been studied. Thus, the reaction was effective with RfCO2K (Rf=CCl3, CF3CF2) and a new route
最近已经开发了通过三氟乙酸盐的热脱羧制备三氟甲基芳基硫化物的新的工业和经济途径。为了合成R f SAr,已经研究了将“三氟脱羧”反应合成为R f CO 2 K(R f:CCl 3,CF 2 Cl,CF 3 CF 2,CF 3 CF 2 CF 2)的可能性。因此,该反应在R f CO 2 K(R f = CCl 3,CF 3 CF 2),并简要举例说明了制备芳基五氟乙基硫化物CF 3 CF 2 SAr的新途径。

Perfluoroalkylation of aliphatic, aromatic and heterocyclic thiols by perfluoroalkyliodides in the presence of Et3N appears to occur spontaneously under daylight or the usual laboratory lighting conditions at 20–22 °C and is complete in 10–15 min to 2–3 h. An exception to this rule are thiols with a low nucleophilicity. The reaction is accompanied by thiol oxidation (2%–3%) and depends directly on
In the reaction of bis(heptafluorobutyryl) peroxide with carbanions and a thiolate anion, two types of reactions were observed; one is an electron transfer reaction to give perfluoropropylated compounds and the other is a nucleophilic substitution.
