摘要

Abstract Tetraalkylammonium and 1, 3-dialkylimidazolium tetrafluoroborates and hexafluorophosphates were employed for the first time as recoverable phase-transfer catalysts in multiphase reactions of CH-acids, in particular in solid base-promoted cross- aldol condensations. The catalysts retained their catalytic activity over several reaction cycles.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
