Abstract

The invention comprises aldehydes of formula CH3CHRCHO, wherein R is a p-chlorophenyl, p-chlorobenzyl, o-chlorobenzyl, p-fluorobenzyl or cyclopentyl group, and the preparation thereof and of compounds in which R is an isopropyl, p-methoxyphenyl, p-tolyl, benzyl or cyclohexyl group by reaction of methoxyacetone in an anhydrous ether with a Grignard reagent of formula RMgBr and hydrolysing the reaction mixture with a saturated aqueous solution of ammonium chloride to form a methoxypropanol of formula CH3CR(OH)CH2OCH3, heating this product in the absence of solvent with an acid sulphonic ion-exchange resin for 1 to 60 hours, and recovering the aldehyde by cooling and filtering off the resin. The products may be characterized by formation of their semicarbazones or 2,4-dinitrophenylhydrazones.
