| titleOfInvention | Process for the preparation of naphthalene derivatives |
| abstract | The present invention relates to a process for the preparation of a compound of the general formula, R-(A1-Z-)m B-CF2O-A2-(A3)n-R' (I) in which R is alkyl, in which one or more CH2 groups may be replaced, independently of one another, by O, CF2, CH=CH, CH=CF or CF=CF, with the proviso that peroxide structures O-O and formaldehyde acetals O-CH2-O are excluded, A1 is, independently of one another, 1,4-cyclohexylene, 2,5-1,3-dioxanylene, 1,3-cyclobutylene or, A2 and A3 are 1,4-phenylene, in which, independently of one another, from one to four hydrogens may be replaced by fluorine or one or two CH groups may be replaced by N, Z is a single bond, -CH2-CH2-, -CF2-CF2-, -CH=CH-, -CF=CF-, -CH=CF- or -CF=CH-, B is 2,6-disubstituted naphthalene, 2,6-disubstituted 5,6,7,8- tetrahydronaphthalene or 2,6-disubstituted trans-decalin, R' is R, F, OCF3, OCF2H, CF3, C1, SF5, CN or NCS, and m and n are, independently of one another, 0 or 1, comprising the following steps: (a) conversion of a compound of the general formula R-(A1-Z-)mBX (II), in which X is halogen or =O and the other symbols are as defined in relation to the formula (I), into a carboxylic acid derivative with elimination of the group X and introduction of a Cl unit; (b) reaction of the carboxylic acid derivative with a phenol of the general formula HO-A2(-A3)n-R' (III), in which A2, A3, R' and n are as defined in relation to the formula (I), to give the compound of the formula (I). |
