Tetraalkylammonium salts bearing PF6- and BF 4- anions have been recognized as recoverable phase-transfer catalysts for the synthesis of 1,1-dichlorocyclopropane and α-(trichloromethyl) carbinol derivatives from alkenes or aldehydes in the heterogeneous system KOH(s)/CHCl3. The catalysts retained their catalytic activity over several reaction cycles. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
