A compound having a structure of the formula Ir(LA)(LB), in which LA is a bidentate, tridentate, tetradentate, pentadentate, or hexadentate ligand and LB is a monodentate, bidentate, tridentate, or tetradentate ligand, or not present, and where the total denticity of LA plus LB is 6, and LA includes at least one structure of Formula I: is disclosed as a useful phosphorescent emitter compound.
A novel one-pot method for the preparation of pyrazoles by 1,3-dipolar cycloadditions of diazo compounds generated in situ

A convenient one-pot procedure for the preparation of pyrazoles by 1,3-dipolar cycloaddition of diazo compounds generated in situ has been developed. Diazo compounds derived from aldehydes were reacted with terminal alkynes to furnish regioselectively 3,5-disubstituted pyrazoles. Furthermore, the reaction of N-vinylimidazole and diazo compounds derived from aldehydes gave exclusively 3-substituted pyrazoles in a one-pot process.
