Patent ID: 8207184

Claim:
A compound represented by Formula (II) below, a tautomer or stereoisomer thereof, or a salt thereof, wherein, X 1 =Y 1 =X 2 =Y 2 =F, or X 1 and Y 1 together form an alkylenedithio group (—S-L 1 -S—, wherein L 1 is an alkylene group), or X 1 and Y 1 together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group, and X 2 and Y 2 are each independently fluorine or an alkylsulfanyl group (alkylthio group), or X 2 and Y 2 together form an alkylenedithio group (—S-L 2 -S—, wherein L 2 is an alkylene group), or X 2 and Y 2 together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group; or X 1 and Y 1 are each independently fluorine or an alkylsulfanyl group (alkylthio group), or X 1 and Y 1 together form an alkylenedithio group (—S-L 1 -S—, wherein L 1 is an alkylene group), or X 1 and Y 1 together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group, or X 2 and Y 2 together form an alkylenedithio group (—S-L 2 -S—, wherein L 2 is an alkylene group), or X 2 and Y 2 together with the carbon atom to which they are attached form a carbonyl group or a thiocarbonyl group; and Z is an atom or an atomic group represented by any one of Formulae (i) to (ii) below, wherein R 1 , R 2 , R 4 to R 6 are each independently a hydrogen atom or a substituent.
