Abstract
PURPOSE: To obtain p-alkoxyphenylpropionaldehydes easily, by the reaction of aldehydes, such as isobutylaldehyde, with p-alkoxybenzyl halides in an alkaline aqueous solution is the presence of a phase-transfer catalyst.
CONSTITUTION: The desired compounds of formula III are obtained by the reaction of aldehydes of formula I (R1,2 are 1W12C hydrocarbon radicals, or R1 and R2 may together form a ring) and halides of formula II (R3 is 1W12C hydrocarbon radical; X is halogen) in an alkaline aqueous solution in the presence of a phase- transfer catalyst, such as organic tert-ammonium salts, organic phosphonium compounds, crown ether compounds, etc. The alkaline aqueous solution is e.g. an aqueous solution of an alkali(ne earth) metal hydroxide. Reaction temperature is below 250°C.
