from 6-(Imidazol-1-yl)- and 6-(1,2,4-Triazol-4-yl)purine Derivatives. —
Nickel-based systems with imidazolium carbene ligands catalyze efficiently the reaction of arylboronic acids and nucleoside derivatives. The reaction of (VII) in the presence of SIPr produces oxygen-insertion by-products, while IPr affords (VIII) exclusively. — (LIU, J.; ROBINS*, M. J.; Org. Lett. 6 (2004) 19, 3421-3423; Dep. Chem.
