Pyrrolotriazole derivative.

摘要

A novel pyrrolotriazole derivative is disclosed, represented by any one of formulae (I), (II), or (III): <CHEM> wherein: R<1>, R<2>, R<3> and R<4> each independently represents a hydrogen atom or a nonmetallic atomic group; R<5> and R<6> each independently represents a hydrogen atom, alkyl group, an aryl group, or a heterocyclic group; R<7> represents an electrophilic group having a Hammett's substituent constant sigma p of 0.15 or more; R<8> and R<9> each independently represents a hydrogen atom or a nonmetallic atomic group; the sum of Hammett's substituent constant sigma p of R<7> and R<8> is 0.65 or more; R<1> and R<2>, and/or R<2> and R<5>, and/or R<5> and R<6>, and/or R<6> and R<3>, and/or R<3> and R<4> may be connected to each other to form a cyclic structure; R<7> and R<8> may be connected to each other to form a cyclic structure; and Z represents a hydrogen atom, a halogen atom, an arylthio group, a heterocyclic thio group, an arylsulfinyl group, or a nitroso group.
