The present invention addresses the problem of providing a compound which enables the formation of a cured article having a small Abbe's number and also having high abnormal dispersion. The present invention also addresses the problem of providing a curable composition, a cured article, an optical member and a lens each of which contains the compound. The present invention relates to a compound represented by general formula (1). X and Y independently represent an oxygen atom, a sulfur atom, a nitrogen atom or a carbon atom; Z represents an atomic group that can form a 5- to 7-membered ring in conjunction with X-C=C-Y; R 1 and R 2 independently represent a hydroxy group, an alkoxy group having 2 to 6 carbon atoms, a mercapto group, a thioalkoxy group having 2 to 6 carbon atoms, an amino group, an alkylamino group having 1 to 6 carbon atoms, a carboxy group, an alkylcarbonyloxy group having 1 to 6 carbon atoms, a carbamoyloxy group or an alkoxycarbonyloxy group having 2 to 6 carbon atoms; and R 3 to R 6 independently represent a substituent. |
