| titleOfInvention | Preparation of 3-arylisobutyl alcohols |
| abstract | 3-Arylisobutanols of the general formula I <IMAGE> (I) where R1 and R2 are each hydrogen or an alkyl or cyclo-alkyl radical of not more than 8 carbon atoms, preferably alkyl of 1 to 4 carbon atoms, are prepared by a process in which an arylcarbinol of the general formula II <IMAGE> (II) is reacted with n-propanol in the presence of a catalytic amount of an alkali metal hydroxide or an alkali metal alcoholate at from 250 DEG to 350 DEG C. in a closed reaction vessel. The process is of particular importance for the preparation of 3-arylisobutanols of the formula I, where R1 is alkyl of 1 to 4 carbon atoms and R2 is hydrogen. The p-methyl-, p-isopropyl- and p-tert-butylphenylisobutanols obtained here in very good selectivity are useful intermediates for the desirable scents jasmorange, cyclamen aldehyde and Lysmeral TM (Lilial TM ). |
