Electrophilic, catalytic alkylation of polyfluoroolefins by some fluoroalkanes
摘要:
New data are presented on the antimony pentafluoride catalyzed reaction of hydrofluorocarbons such as CH3F, CH2F2, CH3CHF2 and RfCH2CH2F with fluoroolefins. The condensation of CH2F2 and fluoroolefins CF2=CFX (X = F, CF3) proceeds under mild conditions producing the corresponding propanes FCH2CFXCF3, in moderate to high yield. Under similar conditions methyl fluoride reacts with tetrafluoroethylene giving CH3CF2CF3. However, a complex mixture of products forms in the analogous reaction with hexafluoropropene. The structures of the products of the reactions of CH3CHF2 and tetrafluoroethylene: and F-butylethylene were determined. (C) 2001 Elsevier Science B.V. All rights reserved.
