| titleOfInvention | Process for preparing m- or p-substituted phenylalkanols by alkylation |
| abstract | The subject of the present invention is that R 1 is bonded to the phenyl ring at the m-position or p-position and represents C 1 -C 5 alkyl, and R 2 , R 3 , R 4 and R 5 are independently of one another hydrogen. Or a process for preparing m- or p-substituted phenylalkanols of formula (I) representing methyl, wherein R 2 , R 3 , R 4 and R 5 have the meanings described in formula (I) An unsubstituted phenylalkanol of formula (II) is represented by the formula (III) R 1 -Hal (III), wherein R 1 has the meaning described in formula (I) and Hal represents halogen. Alkylation in the presence of a Friedel-Crafts catalyst together with the indicated C 1 -C 5 alkyl halide to give m- or p-alkyl substituted phenylalkanols of formula (I) and subsequently the reaction mixture is worked up. And the desired m in formula (I) Alternatively, the p-alkyl substituted phenylalkanol is separated and the remaining formed byproduct is returned to the reaction mixture and the byproduct is isomerized in the presence of Friedel-Crafts catalyst to produce the desired m- or p A process for preparing m- or p-substituted phenylalkanols of the formula (I), characterized in that they give rise to alkyl-substituted phenylalkanols. Oxidation or dehydrogenation from m- or p-alkyl substituted phenylalkanols of formula (I) can form the corresponding aldehydes as valuable products, which aldehydes have an interesting role as odorants and perfumes. play. |
