- Synthesis method of 4-(4'-alkylcyclohexyl)cyclohexanol
-
The invention discloses a novel method for synthesizing cis-trans mixed 4-(4'-alkylcyclohexyl)cyclohexanol by taking biphenyl as a starting raw material through five steps of reactions including Friedel-Crafts acylation reaction, Friedel-Crafts alkylation reaction, reduction reaction, oxidation reaction and catalytic hydrogenation. The method is mild in reaction condition, good in selectivity, high in yield, convenient to operate, environmentally friendly and suitable for industrial production.
