Abstract

A substituted benzene derivative represented by a formula: ##STR1## where A represents: ##STR2## wherein X is a hydrogen atom, a halogen atom or a nitro group, R.sup.1 is --X.sup.1 Z.sup.1 (X.sup.1 is an oxygen atom or a sulfur atom and Z.sup.1 is a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group), --COZ.sup.1 group (Z.sup.1 is as defined above), ##STR3## group (Z.sup.1 is as defined above, Z.sup.2 is --CO.sub.2 Z.sup.3 wherein Z.sup.3 is the same as Z.sup.1, or --SO.sub.2 Z.sup.3 wherein Z.sup.3 is as defined above and n is 0 or 1), ##STR4## (Z.sup.1 and Z.sup.3 are as defined above) or ##STR5## (X.sup.2, X.sup.3 and X.sup.4 are, respectively, an oxygen atom or a sulfur atom and Z.sup.4 and Z.sup.5 are the same as Z.sup.1), and R.sup.3 is a nitro group or ##STR6## (R.sup.4 and R.sup.5 are, respectively, an alkyl group, or they may form a heterocyclic group together with the adjacent nitrogen atom), or ##STR7## wherein X and R.sup.3 are as defined above and R.sup.2 is --X.sup.1 Z.sup.1 (X.sup.1 and Z.sup.1 are as defined above); Y is a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkylthio group, a nitro group or ##STR8## (R.sup.6 and R.sup.7 are, respectively, a substituted or unsubstituted alkyl group); R is ##STR9## (R.sup.8 is the same as Y and q is an integer of 1 to 4), ##STR10## (R.sup.8 is as defined above, and r is an integer of 1 to 3) or ##STR11## (R.sup.8 and r are defined above); and m is an integer, of 1 to 4, or its salt.
