Patent ID: 8901323

Claim:
A ruthenium complex represented by the following general formula (1*): wherein each * represents an asymmetric carbon atom, R 1 represents an alkyl group having 1 to 10 carbon atoms; an alkanesulfonyl group having 1 to 10 carbon atoms and optionally substituted with a halogen atom; an arenesulfonyl group optionally substituted with an alkyl group having 1 to 10 carbon atoms, a halogenated alkyl group having 1 to 10 carbon atoms, or a halogen atom; an alkoxycarbonyl group having 2 to 11 carbon atoms in total; or a benzoyl group optionally substituted with an alkyl group having 1 to 10 carbon atoms, R 2 and R 3 each independently represent an alkyl group having 1 to 10 carbon atoms; a phenyl group optionally substituted with an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, or a halogen atom; or a cycloalkyl group having 3 to 8 carbon atoms, or R 2 and R 3 may together form a ring, R 10 , R 12 , and R 14 each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, or a trisubstituted alkylsilyl group, R 11 and R 13 each independently represent a hydrogen atom, an alkyl group having 2 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, or a trisubstituted alkylsilyl group, provided that the case where all of R 10 to R 14 simultaneously represent hydrogen atoms is excluded, X represents a trifluoromethanesulfonyloxy group, a p-toluenesulfonyloxy group, a methanesulfonyloxy group, a benzenesulfonyloxy group, a hydrogen atom, or a halogen atom, j and k each represent 0 or 1, and j+k is 0 or 2.
