Cyclometalated iridium(III) complexes based on phenyl-imidazole ligand
Phenyl-imidazole-based ligands with various substitution patterns have been used as the main ligand for heteroleptic bis-cyclometalated iridium complexes. Two series of complexes have been prepared and their photophysical and electrochemical properties we
Palladium-catalyzed desulfitative C-H arylation of heteroarenes with sodium sulfinates
Desulfitative C-H arylation: Palladium-catalyzed desulfitative C-H arylation of heteroarenes with sodium sulfinates has been disclosed to construct aryl-heteroaryl bonds without the need for any extra ligands (see scheme). Copyright
Synthesis and single-crystal X-ray diffraction studies of new cyclometallated phenylimidazole palladium(II) compounds
Cyclometallation of 1,4,5-trimethyl-2-phenylimidazole, L, with Pd(OAc)2 gave exclusively the dinuclear anti isomer with bridging acetate ligands, 1. Subsequent treatment of 1 with sodium chloride gave the corresponding dinuclear compound with b

Synthesis of imidazoles via hetero-cope rearrangements
A novel synthetic approach to heterocycles containing the imidazole moiety based on the multihetero-Cope rearrangement is described. Oximes are reacted with benzenecarboximidoyl chlorides 4 affording adducts that readily undergo the hetero-Cope rearrangement at slightly elevated temperatures. Acid treatment of the resulting amidines 8 provides imidazoles in very high yields.
