Vinylnosylates, readily obtained from β-dicarbonyl derivatives, could be efficiently engaged in Sonogashira cross-couplingreactions, either cocatalyzed by copper or silver salts. The para-nitrobenzenesulfonate (nosylate) group allows this coupling to be performed under very mild conditions (room temperature). These new leaving group and mild conditions could be applied to the synthesis of acetylenic

Vinylnosylates derived from 1,3-dicarbonyl compounds could be engaged in Suzuki–Myaura cross coupling reactions with aryl-, vinyl- and methylboronic acids or trifluoborate derivatives at room temperature in the presence of 2 mol% of [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) [PdCl2(dppf)]. One-pot procedures have been set up for practical and efficient nosylation–cross-coupling reactions
