experimental part, p. 2251 - 2261 (2009/08/09)
Catalytic activities of NHC-derived nickel-pincer complexes for the Suzuki-Miyaura coupling reactions of aryl/alkenyl to- sylates and mesylates are described. In the presence of a catalytic amount of nickelacycle 1a, a wide array of tosylates and mesylates reacted with several aryl- and alkenylboronic acids to afford the coupling products, generally in high yields. Fine tuning of the reaction conditions for each class of electrophiles was achieved only by choosing the appropriate reaction medium (DME for tosylates, dioxane for mesylates).
Efficient route to 4-substituted-2(5H)-furanones, 2(1H)-quinolones, and pyrones by nickel-catalyzed cross-coupling of arenesulfonates with organozinc reagents

Nickel(II)-catalyzed cross-coupling reactions of 4-tosyl-2(1H)-quinolone, pyrone, and 2(5H)-furanone with various organozinc reagents provide an efficient and practical method for the high-yielding synthesis of 4-substituted 2(1H)-quinolones, pyrones, and 2(5H)-furanones. Copyright

, p. 1305 - 1324 (2007/10/02)
4-Hydroxy-2-quinolones 1 are generally found to be converted to the 4-azidocompounds 3 via the 4-chloroquinolones 2, the 4-tosyloxyquinolones 6, or the 4-aminoquinolones 4, respectively.Choice of the reaction conditions and yields depend on the substituen
