Method for producing cyclometalated iridium complex, and cyclometalated iridium complex precursor including organoiridium material

A method for producing a cyclometalated iridium complex represented by the following Formula (3), the method comprising producing a cyclometalated iridium complex by reacting a cyclometalated iridium complex raw material including an organoiridium material represented by the following Formula (1) with an aromatic heterocyclic bidentate ligand capable of forming an iridium-carbon bond and represented by the following Formula (2) and an iridium-nitrogen bond,

• wherein the aromatic heterocyclic bidentate ligand represented by the Formula (2) is reacted with 1.5 times or more and less than 3 times the molar amount of the iridium compound represented by the Formula (1);
• (in Formula (1), Ir represents an iridium atom, and O represents an oxygen atom;
• L represents a ligand capable of forming an iridium-oxygen bond;
• R1, R3, R4, R6, R7 and R9 each independently represent an alkyl group;
• R2, R5 and R8 each independently represent a hydrogen atom or an alkyl group;
• and some or all of hydrogen atoms of the alkyl group may be substituted with halogen atoms),
• (in Formula (2), N represents a nitrogen atom, C represents a carbon atom, H represents a hydrogen atom, CyA represents a five-membered or six-membered cyclic group containing nitrogen atoms, CyB represents a five-membered or six-membered cyclic group containing carbon atoms, and CyA and CyB may be linked together to form a ring structure), and
• (in Formula (3), Ir represents an iridium atom, N represents a nitrogen atom, C represents a carbon atom, CyA represents a five-membered or six-membered cyclic group containing nitrogen atoms, and is linked to iridium via the nitrogen atoms, and CyB represents a five-membered or six-membered cyclic group containing carbon atoms, and is linked to iridium via the carbon atoms;
• CyA and CyB may be linked together to further form a ring structure;
• R10 and R12 each independently represent an alkyl group, R11s each independently represent a hydrogen atom or an alkyl group, and some or all of hydrogen atoms of the alkyl group may be substituted with halogen atoms;
