ChemInform Abstract: Recoverable Phase‐Transfer Catalysts with Fluorinated Anions: Generation and Reactions of Dichlorocarbene and CCl₃ Anion in the Heterogeneous System KOH(s)/CHCl₃/nBu₄NPF₆.

Abstract

System KOH(s)/CHCl3/nBu4NPF6. -Bu4NPF6 is applied as efficient phase-transfer catalyst for dichlorocyclopropanation and trichloromethylation reactions. It is easily separated from the reaction products and used repeatedly over several reaction cycles (to be continued). -(KRYSHTAL, G. V.; ZHDANKINA, G. M.; ZLOTIN*, S. G.; Eur.
