Fluorinated ketenedithioacetals. 5. A new synthesis of perfluoroketenedithioacetals from alkyl perfluoroalkanedithiocarboxylates
摘要:
The title compounds were synthesized by reaction of organometallic reagents with alkyl perfluoroalkanedithiocarboxylates via a thiophilic attack and a subsequent elimination of the alpha-fluoride. (C) 1997 Published by Elsevier Science Ltd.
Polyfluoroalkyldithiocarboxylates react with dimethylacetylenedicarboxylate (DMAD) to give 2-polyfluoroalkyl-1,3-dithioles and/or 2-polyfluoroalkylidene-1,3-dithioles depending on the substituent at the thiolic sulfur atom and on the length of the polyfluoroalkyl chain. Amides of polyfluoroalkylthioncarboxylic acids with DMAD give 2-methoxy-2-polyfluoroalkyl-5-methoxycarbonylmethylene-thiazolidin-4-ones
