  • Patent number: 8212048
    Abstract: A method of producing an aromatic compound of the following formula (3) comprising reacting a compound of the following formula (1) with an olefin compound of the following formula (2) in the presence of a transition metal complex: (wherein, an Ar1 ring represents an aromatic hydrocarbon ring or aromatic heterocyclic ring, an Ar2 ring represents a heterocyclic ring containing X1 and N*, and the X1 represents a nitrogen atom or carbon atom and the N represents a nitrogen atom connecting via a double bond to either one of two adjacent atoms in the Ar2 ring.) (wherein, R1, R2, R3 and R4 represent each independently a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 18 carbon atoms.) (wherein, Ar1, Ar2, X1, N*, R1, R2 and R3 represent the same meanings as described above.).

  • Publication number: 20120012822
    Abstract: An aromatic compound represented by the following formula (1). [In the formula, ring A and ring B each represent a benzene ring, an aromatic fused ring composed of 2-4 rings, a heteroaromatic ring or a heterocyclic aromatic fused ring composed of 2-4 rings, R1a represents a group —CHR2a—CHR2bR2c, and R1b, R1c and R1d each represent hydrogen, aryl or a group —CHR2d—CHR2eR2f. This is with the proviso that at least 2 of R1b, R1c and R1d are not hydrogen. R2a, R2b and R2c each represent hydrogen, alkyl, aryl or a substituted silyl group, and R2a and R2b may be bonded together to form a ring. R2d, R2e and R2f each represent hydrogen, alkyl, aryl or a substituted silyl group, and R2d and R2e may be bonded together to form a ring.

  • Publication number: 20110308963
    Abstract: In an electrolytic bath partitioned with an anion exchange membrane, water is supplied to the cathode chamber and an aromatic compound and a polar organic solvent, and depending on the case also a transition metal catalyst, are supplied to the anode chamber, and then electrolysis is carried out in the presence of a halogenating agent, to introduce a halogen onto the aromatic ring of the aromatic compound.

  • Publication number: 20110213163
    Abstract: A compound represented by the following formula (1): wherein Ar1, Ar2 and Ar3 each independently represent an aryl group or a monovalent heterocyclic group; the aryl group or the monovalent heterocyclic group represented by Ar1 has an aryl group, a monovalent alicyclic hydrocarbon group or a monovalent heterocyclic group at one position adjacent to the atom that forms Ar1 and is bonded to a carbon atom forming the benzene ring Q; the aryl group or the monovalent heterocyclic group represented by Ar2 has an aryl group, a monovalent alicyclic hydrocarbon group or a monovalent heterocyclic group at one position adjacent to the atom that forms Ar2 and is bonded to a carbon atom forming the benzene ring Q; the aryl group or the monovalent heterocyclic group represented by Ar3 has an aryl group, a monovalent alicyclic hydrocarbon group or a monovalent heterocyclic group at one position adjacent to the atom that forms Ar3 and is bonded to a carbon atom forming the benzene ring Q.
