PROBLEM TO BE SOLVED: To provide an organometallic complex which can convert a triplet excited state to light emission. SOLUTION: The present invention provides an organometallic complex having a structure represented by general formula (G7) where R1 is a branched alkyl group having carbon atoms of 4 or more with straight chain carbon atoms of 3 or more, or an alkyl group having carbon atoms of 5-10, R2 is hydrogen, an alkyl group having carbon atoms of 1-6, or a phenyl group, R3 is hydrogen or an alkyl group having carbon atoms of 1-6, R4-R7 are independently hydrogen, an alkyl group having carbon atoms of 1-6, an alkoxy group having carbon atoms of 1-6, an alkylthio group having carbon atoms of 1-6, a halogen group, a haloalkyl group having carbon atoms of 1-6, or an aryl group having carbon atoms of 1-6, M is central metal and represents a group 9 element or a group 10 element.

High-yielding oxidation of β-hydroxyketones to β-diketones using o-Iodoxybenzoic acid
Bartlett, Samuel L.,Beaudry, Christopher M.
experimental part, p. 9852 - 9855 (2012/01/02)
The oxidation of β-hydroxyketones to β-diketones was systematically investigated. o-Iodoxybenzoic acid (IBX) was found to be efficient, operationally easy, and superior to other common oxidants. The reaction is suitable for milligram- to gram-scale oxidations.
A novel synthesis of 1,3-diketones by reaction of an α-bromoketone with acyl chlorides promoted by gallium triiodide

, p. 666 - 667 (2007/10/03)
Promoted by gallium triiodide, an α-bromoketone, bromomethyl phenyl ketone, is treated with acyl chlorides to synthesize 1,3-diketones in good yields under mild and neutral conditions.
