Cu-Catalyzed three-component coupling reactions using nitriles, 1,3-dienes and silylboranes
Fujihara, Tetsuaki,Matsuda, Yuki,Tsuji, Yasushi
, p. 4648 - 4651 (2020)
This paper reports novel Cu-catalyzed three-component coupling reactions using nitriles, 1,3-dienes and silylboranes. The desired reactions proceed at room temperature and yield β,γ-unsaturated ketones with a (dimethylphenylsilyl)methyl moiety at the α-po

A nickel-catalyzed protocol for the conversion of aryl and heteroaryl alcohol derivatives to primary and secondary aromatic amines via C(sp2)-O bond cleavage is described. The new amination protocol can be applied to a range of substrates bearing diverse functional groups and uses readily available benzophenone imines as an effective nitrogen source.
Copper-Mediated Functionalization of Aryl Trifluoroborates

This paper describes the Cu(OTf)2-mediated coupling of aryl and heteroaryl trifluoroborates with tetrabutylammonium or alkali metal salts to form C-O, C-N, and C-halogen bonds. The reactions proceed under mild conditions (often room temperature over 16 hours) with carboxylate, halide, and azide salts, all nucleophiles that have been underrepresented in the copper cross-coupling literature. Preliminary results show that copper salts bearing weakly coordinating X-type ligands are essential for enabling these transformations to proceed under mild conditions.
