Patent ID: 7932398

Claim:
A substituted phenylethynylgold-nitrogen-containing heterocyclic carbene complex represented by the following general formula (1) or (2): wherein L represents a nitrogen-containing heterocyclic carbene ligand represented by the following the general formula (3) or (4): wherein each of R 1 and R 2 independently represents an alkyl group, a cycloalkyl group, a polycycloalkyl group or an aryl group, and each of R 3 , R 4 , R 5 and R 6 independently represents a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, a nitro group, a cyano group or a dialkylamino group; the adjacent groups in R 3 , R 4 , R 5 and R 6 are optionally bonded together, so that the adjacent groups and the carbon atom(s) to which the groups are bonded together form a ring; and, when R 1 to R 6 represent a group containing a carbon atom(s), one hydrogen atom or a plurality of hydrogen atoms on the carbon atom(s) of the group are optionally replaced by a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxy group or an aryloxy group, and X represents an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group, a heterocyclic group, an alkoxy group, an aryloxy group, an alkylmercapto group, an arylmercapto group or a substituted amino group and one hydrogen atom or a plurality of hydrogen atoms on the carbon atom(s) of X are independently optionally replaced by a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, an alkylmercapto group, an arylmercapto group or a substituted amino group.
