A novel Pd(OAc)2-catalyzed methylation reaction by dicumylperoxide via aryl C−H bond activation was discovered. Various 2-phenylpyridine and acetanilides can be used as reactants in these reactions. Peroxide was used as both the methylatingreagent and the hydrogenacceptor.

alkylation of arenes using commercially available alkyltrifluoroborates is disclosed. Oximes, heteroarenes, azomethines, N-nitrosoamines, and amides are viable directing groups to entail this transformation. The alkyl group in the boron reagent can be extended to primary alkyls, benzyl, and cycloalkyls, and the reaction proceeded with controllable mono- and dialkylation selectivity when both ortho C–H
Rhodium-electrocatalyzed C−H alkylation of N-heteroarenes has been established by using sustainable and eco-friendly electrocatalytic approaches. As a result, several arenes, including biologically relevant purines, diazepam, and amino acids were selectively methylated. Finally, an example of an unprecedented, paired electrolysis approach leading to ethylated and propylated arenes was also discovered
The invention provides a method for producing an iridium complex with a high yield at a low temperature, and an organic electroluminescence device (organic EL device) having an light output high in efficiency and high luminance in a range from blue to red region. An iridium complex for the organic EL device is produced from an iridium complex having a 4-membered ring structure as an auxiliary ligand. The organic EL device is composed of at least a pair of electrodes serving as an anode and a cathode, and an organic compound layer interposed between the electrodes, and the organic compound layer contains an iridium complex represented by a following structure:
