Patent ID: 8008336

Claim:
A compound represented by Formula (II) below, a tautomer or stereoisomer thereof, or a salt thereof, wherein all of X 1 , Y 1 , X 2 , and Y 2 are a fluorine atom; 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 a carbon atom to which X 1 and Y 1 are attached form a carbonyl group or a thiocarbonyl group, and X 2 and Y 2 are each independently, a fluorine atom or an alkylsulfanyl group (alkylthio group), or X 2 and Y 2 together form a alkylenedithio group (—S-L 2 -S—, wherein L 2 is an alkylene group), or X 2 and Y 2 together with a carbon atom to which X 2 and Y 2 are attached form a carbonyl group or a thiocarbonyl group; or X 1 and Y 1 are each independently, a fluorine atom 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 a carbon atom to which X 1 and Y 1 are attached form a carbonyl group or a thiocarbonyl group, and X 2 and Y 2 together form a alkylenedithio group (—S-L 2 -S—, wherein L 2 is an alkylene group), or X 2 and Y 2 together with a carbon atom to which X 2 and Y 2 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 (vii), wherein R 1 to R 3 are each independently, a hydrogen atom or a substituent.
