| 摘要 |
The invention relates to a method for producing 4'-alkyl-4-hydroxy-biphenyl derivatives of the formula (I), wherein A represents an alkyl with 1-10 C atoms, wherein one or two CH2 groups may be substituted by O atoms or -CH=CH groups, by reacting, by means of a Grignard reaction, a compound of the formula (II), wherein Hal represents Cl, Br or I and A' represents an alkyl with 1-8 C atoms, wherein one or two CH2 groups may be substituted by O atoms or -CH=CH, with a compound of the formula (III): A-L, wherein A has the meaning indicated above and L represents Cl, Br, I, OH or a reactive esterified OH group, to give a compound of the formula (IV), wherein A and A' have the meanings indicated above, and subsequent ether cleavage. |
