Reaction of 2-(dichloromethyl)furan (I) with KOH in a CH2Cl2 medium and in the presence of alcohols (methanol, ethanol, and n-butanol) and a catalytic amount of triethylbenzylammonium chloride (TEBAC) results in the formation of 2-chloromethylene-5-alkoxy-2,5-dihydrofurans (II) (mixtures of Z- and E-siomers) and 2-dialkoxymethylfurans (III), in overall yields of up to 96%. Reaction with isopropyl and tert-butyl alcohols gave only the corresponding products (II), in 21 and 12% yield, respectively.
