NaBHT (sodium 2,6-di-tert-butyl-4-methylphenolate), a strong, but hindered and lipophilic base, has been effectively paired with similarly lipophilic, high-reactivity Pd-NHC (N-heterocyclic carbene) catalysts to produce an ideal combination for performing solvent-free (melt) cross-coupling amination. The mild nucleophilicity of NaBHT, coupled with the anti-oxidant properties of its conjugate acid byproduct

dual catalytic nickel/ruthenium system from aryl azides and arylelectrophiles. Photoreduction of the aryl azide is proposed to proceed through an arylnickel-azide complex, which upon reduction and loss of nitrogen, generates a nickel(III) species capable of facile reductive elimination to afford the desired C–N bond formation. A variety of functionalized (hetero)arylelectrophiles are shown to participate

An efficient and general selective method for the synthesis of 8-aminoquinoline derivatives has been disclosed through transition metal direct C–N coupling from fluoroquinolines and arylamines. Significantly, good chemo- and regio-selectivity was observed for polyfluoroquinolines in which only C–F bond on 8-substituted position was broken. Thus, this methodology proves its value as an inexpensive and
