1. A dicarbene transition metal complex of formula (1): wherein: M represents a transition metal element selected from the group consisting of Group 8 to Group 12 transition metal elements in the periodic table, wherein the transition metal element represented by M is in any oxidation state; K represents an uncharged monodentate or bidentate ligand; L represents a monodentate or bidentate monoanionic or dianionic ligand; m represents an integer from 0 to 5; o represents an integer from 0 to 5; n represents an integer from 1 to 3; p represents the number of charges in the complex which is represented by an integer from 0 to 4; W— represents a monoanionic counterion; wherein: m, o, n, and p are dependent on the oxidation state and coordination number of the transition metal element represented by M or on the charge on ligands and the charge on the entire complex; Y1, Y2, Y3, and Y4 each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, a heterocycloalkyl group, an aryl group, a heteroaryl group, an aralkyl group, an alkenyl group, an alkynyl group, or an alkoxy group, wherein each group is optionally substituted or unsubstituted; and wherein Y1 and Y2, Y2 and Y3, and Y3 and Y4,independently of one another, are optionally bonded and integrated to form a saturated or unsaturated ring structure having at least two atoms between nitrogen atoms, wherein one or more atoms of the ring structure are optionally substituted with an alkyl group or an aryl group, and a substituent thereof is optionally further substituted or unsubstituted, and the ring structure optionally forms one or more further ring structures; and R1 and R2 each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, a heterocycloalkyl group, an aryl group, an aralkyl group, a heteroaryl group, an alkenyl group, an alkynyl group, or an alkoxy group, where each group is optionally substituted or unsubstituted. |
