The present invention provides an organometallic complex having a high quantum efficiency even in a polymer thin film as a emitting material for organic electroluminescent (EL) element. The present invention relates to an organoiridium complex for an organic electroluminescent element represented by the following Formula; wherein a C—N ligand including two atomic groups (A
1
, A
2
), and a β-diketone ligand in line symmetry having two tert-butyl-substituted phenyl groups are coordinated with an iridium atom. The organoiridium complex of the present invention has a high quantum efficiency even in a polymer thin film with respect to green to yellow electroluminescence.
(In the aforementioned Formula, R
1
, R
2
, and R
3
are each a tert-butyl group or a hydrogen atom, and have at least one tert-butyl group; they may bond each other to thereby form a saturated hydrocarbon ring, when having two tert-butyl groups; A
1
, A
2
are each an unsaturated hydrocarbon ring, at least one is a single ring, and at least one is a heterocyclic ring.)

[Ir(cod)Cl]<sub>2</sub>/FDPPE-Catalyzed Chemo- and Regioselective Cyclotrimerization of Two Different Terminal Alkynes To Give 1,3,5-Trisubstituted Benzenes
[Ir(cod)Cl] 2 in combination with 1,2-bis(dipentafluorophenylphosphino)ethane catalyzes chemo- and regioselectivecyclotrimerization of two different alkynes. The reaction of methyl propiolate with 1-hexyne gave methyl 3,5-di( N-butyl)benzoate as a single product in 88% yield.
