Patent ID: 7199251

Claim:
A process for producing compounds represented by general formula (I), wherein, m denotes an integer from 1 to 5, Ar denotes a member selected from the group consisting of 1,4-phenylene and 2,7-fluorenylene, in each case optionally substituted with a member selected from the group consisting of linear or branched C 1 –C 20 alkyl residues, and linear C 1 –C 20 alkyl residues interrupted by at least one O atom, R 1 denotes a member selected from the group consisting of H, linear or branched C 1 –C 20 alkyl groups, linear C 1 –C 20 alkyl groups interrupted by at least one O atom, linear C 1 –C 20 alkyl groups interrupted by at least one S atom, silylene groups, phosphonoyl groups, phosphoryl groups, and C 3 –C 20 alkenyl groups, R A , R B independently of one another, and independently for each n, are each selected from the group consisting of H, a linear or branched C 1 –C 20 alkyl group, a linear or branched C 1 –C 20 alkyl group interrupted with 1 to 10 oxygen atoms, a C 1 –C 20 alkoxy group, and together form a C 1 –C 6 dioxyalkylene ring, and n denotes 2, 3 or 4, said process comprising reacting, a compound represented by general formula (II), wherein, n, R 1 , R A and R B are each as described in general formula (I), with a compound represented by general formula (III), wherein, m and Ar are each as described in general formula (I), and Y denotes a member selected from the group consisting of Cl; Br; I; and O—SO 2 —R C , in which R C represents a phenyl, tolyl, methyl or trifluoromethyl, said reaction being performed, optionally in the presence of catalysts, optionally in a solution, and optionally at an elevated temperature.
