PROBLEM TO BE SOLVED: To provide a ligand for a polymerization catalyst. SOLUTION: The substituted benzene is represented by general formula (1) [wherein, A is an atom of group 16 in the periodic table of elements; B<SP>1</SP>and B<SP>2</SP>are each independently an atom of group 15 in the periodic table of the elements (with the proviso that B<SP>1</SP>and B<SP>2</SP>are not simultaneously a nitrogen atom); R<SP>1</SP>to R<SP>7</SP>are each independently a hydrogen atom, a halogen atom, a 1-20C alkyl group, a 7-20C aralkyl group, a 6-20C aryl group, a 1-20C substituted silyl group, a 1-20C alkoxy group, a 7-20C aralkyloxy group, a 6-20C aryloxy group or a 2-20C disubstituted amino group, and neighboring R<SP>1</SP>to R<SP>6</SP>may form a ring by arbitrary bonding to each other].
