A substituted benzene derivative represented by a formula:n where A represents:n wherein X is a hydrogen atom, a halogen atom or a nitro group, R¹ is -X¹Z¹ (X¹ is an oxygen atom or a sulfur atom and Z¹ is a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substitute or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group), -COZ¹ group (Z¹ is as defined above),n group (Z¹ is as defined above, Z² is -CO₂Z³ wherein Z³ is the same as Z¹, or -SO₂Z³ wherein Z³ is as defined above and n is 0 or 1),n (Z¹ and Z³ are as defined above) orn (X², X³ and X⁴ are, respectively, an oxygen atom or a sulfur atom and Z⁴ and Z⁵ are the same as Z¹), and R³ is a nitro group orn (R⁴ and R⁵ are, respectively, an alkyl group, or they may form a heterocyclic group together with the adjacent nitrogen atom), orn wherein X and R³ are as defined above and R² is -X¹Z¹ (X¹ and Z¹ are as defined above); Y is a halogen atom, a subsituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkythio group, a nitro group orn (R⁶ and R⁷ are, respectively, a substituted or unsubstituted alkyl group); R isn (R⁸ is the same as Y and q is an integer of 1 to 4),n (R⁸ is as defined above, and r is an integer of 1 to 3) orn (R⁸ and r are as defined above); and m is an integer of 1 to 4, or its salt. |
