Self-condensation of crotonaldehyde under base-catalyzed phase-transfer conditions leads to aldehydes 3 or 4, depending only on the concentration of aqueous hydroxide used.Quaternary ammonium fluorides in anhydrous THF is shown to be a useful system for conjugate additions involving base-sensitive aldehydes.
