Abstract

PURPOSE: To obtain an acetal, smoothly, in high yield, under mild conditions, by the reaction of a carbonyl compound with alkoxysilane as an acetalization agent in the presence of trialkylsilyltrihalomethane sulfonate etc. as a catalyst.
CONSTITUTION: An acetal is obtained by the reaction of a carbonyl compound (e.g. alicyclic ketones such as cyclopentanone, aromatic aldehydes such as benzaldehyde, etc.) with alkoxysilane (e.g. methoxytrimethylsilane, benzoxytrimethylsilane, 1,2- bistrimethylsiloxyethane, etc.) as an acetalization agent in the presence of a catalyst (e.g. trimethylsilyltrifluoromethane, etc.). The acetal obtained is e.g. benzaldehyde dimethylacetal, cyclopentanone dimethylacetal, etc. The reaction is carried out in an organic solvent, pref. a halogenated hydrocarbon, at -80W+25°C.
