Compound, curable composition, cured product, optical member, and lens

A compound represented by Formula (1),

• in Formula (1), X and Y each independently represents an oxygen atom, a sulfur atom, a nitrogen atom, or a carbon atom, at least one of X or Y is an oxygen atom, a sulfur atom, or a nitrogen atom;
• Z is an atomic group that forms a 5 to 7-membered ring together with X—C═C—Y and represents an atomic group including at least one selected from a carbon atom and a heteroatom;
• R1 and R2 each independently represents a hydroxyl group, an alkoxy group having 2 to 6 carbon atoms that may have a substituent, a mercapto group, a thioalkoxy group having 2 to 6 carbon atoms that may have a substituent, an amino group, an alkylamino group having 1 to 6 carbon atoms that may have a substituent, a carboxy group, an alkylcarbonyloxy group having 1 to 6 carbon atoms that may have a substituent, a carbamoyloxy group that may have a substituent, or an alkoxycarbonyloxy group having 2 to 6 carbon atoms that may have a substituent;
• R3 to R5 each independently represents a halogen atom, a halogenated alkyl group, an alkyl group, an alkenyl group, an acyl group, a hydroxyl group, a hydroxyalkyl group, an alkoxy group, an aryl group, a heteroaryl group, an alicyclic group, or a cyano group;
• R6 represents a halogen atom, a halogenated alkyl group, an alkyl group, an alkenyl group, an acyl group, a hydroxyl group, a hydroxyalkyl group, an alkoxy group, an aryl group, a heteroaryl group, an alicyclic group, or a cyano group;
• m and n each independently represents an integer of 1 to 5, q and r each independently represents an integer of 0 to 4;
• here, 1≤m+q≤5, and 1≤n+r≤5 are satisfied;
• v is an integer of 0 to 4, w is an integer of 0 or more, the maximum number of w is the maximum number of substituents that may be substituted with a ring formed by X—C═C—Y and Z;
• in a case where q is an integer of 2 to 4, the plurality of R3's may be identical to or different from each other, and the plurality of R3's may be bonded to each other to form a ring;
• in a case where r is an integer of 2 to 4, the plurality of R4's may be identical to or different from each other, and the plurality of R4's may be bonded to each other to form a ring;
• in a case where v is an integer of 2 to 4, the plurality of R5's may be identical to or different from each other, but the plurality of R5's are not bonded to each other to form a ring;
• and
• in a case where w is an integer of 2 to 5, the plurality of R6's may be identical to or different from each other, and the plurality of R6's may be bonded to each other to form a ring, provided that in a case where a plurality of R6's are bonded to each other and are groups for forming a fused ring together with a substituted ring, the number of rings for forming a fused ring is 2.
