Patent ID: 6849752

Claim:
A process for synthesizing an ionic metal complex represented by formula (1), the process comprising: reacting in an organic solvent a compound represented by formula (2) with a halogen-containing compound represented by formula (3) or (4), in the presence of a reaction aid comprising an element selected from the group consisting of elements of groups 1-4 and 11-14 of the periodic table, the reaction aid being a compound selected from the group consisting of chlorides, bromides, iodides, alkoxides, and carboxy compounds, wherein M represents a transition metal selected from the group consisting of elements of groups 3-11 of the periodic table, or an element selected from the group consisting of elements of groups 12, 13 and 15 of the periodic table; A a+ represents a metal ion, hydrogen ion or onium ion; a represents a number from 1 to 3; b represents a number from 1 to 3; p is b/a; m represents a number from 1 to 4; n represents a number from 0 to 8; q is 0 or 1; R 3 represents a C 1 -C 10 alkylene group, C 1 -C 10 halogenated alkylene group, C 4 -C 20 arylene group or C 4 -C 20 halogenated arylene group, the alkylene and arylene groups of the R 3 optionally having substituents and hetero atoms, one of the R 3 being optionally bonded with another of the R 3 ; R 4 represents a halogen, C 1 -C 10 alkyl group, C 1 -C 10 halogenated alkyl group, C 4 -C 20 aryl group, C 4 -C 20 halogenated aryl group or X 2 R 7 , the alkyl and aryl groups of the R 4 optionally having substituents and hetero atoms, one of the R 4 being optionally bonded with another of the R 4 to form a ring; each of X 1 , X 2 and X 3 independently represents O, S, NR 5 or NR 5 R 6 ; each of R 5 , R 6 and R 7 independently represents a hydrogen, C 1 -C 10 alkyl group, C 1 -C 10 halogenated alkyl group, C 4 -C 20 aryl group, or C 4 -C 20 halogenated aryl group, the alkyl and aryl groups of the R 5 and R 7 optionally having substituents and hetero atoms, one of the R 5 being optionally bonded with another of the R 5 to form a ring, one of the R 7 being optionally bonded with another of the R 7 to form a ring; each of E 1 and E 2 independently represents a hydrogen or alkali metal; and R 8 represents a halogen.
