(Chemical Equation Presentation) Various dihaloazoles can be monoarylated at a single C-X bond with high selectivity via Suzuki coupling. By changing the palladium catalyst employed, the selectivity can be switched for some dihaloazoles, allowing for Suzuki coupling at the other, traditionally less reactive C-X bond. These conditions are applicable to coupling of a wide variety of aryl-, heteroaryl-, cyclopropyl-, and vinylboronic acids with high selectivities and enable the rapid construction of diverse arrays of diarylazoles in a modular fashion.

Methods have been developed for the synthesis of new ligands bearing imidazole groups.Tris(imidazolyl)ethane and tris(imidazolyl)butane derivatives have a more expanded geometry than the known tris(imidazolyl)carbinols, leading in at least one case to bet
