A tBu₃P-coordinated 2-phenylaniline-based palladacycle complex was demonstrated to be an efficient precatalyst for Pd-catalyzed coupling reactions of aryl halides with polyfluoroarenes that operates through a C–H activation strategy. The ready accessibility and ease of handling of the complex and the high yields of the reaction makes this palladacycle complex an attractive precatalyst for the cross-coupling reaction of aryl halides with polyfluoroarenes.

Aldol condensation of aldehydes with methyl ketones followed by anionic four-electron donor-based (type I) platinacycle-catalyzed addition reactions of arylboronic acids to form β-arylated ketones is described. Good to excellent yields of β-arylated ketones were obtained for the tandem reactions of aromatic/aliphatic aldehydes, methyl ketones, and arylboronic acids, and moderate yields were observed for the tandem reactions of α,β-unsaturated aldehydes.

The asymmetric allylboration of aldehydes with pinacolallylboronates catalyzed by 1,1′-spirobiindane-7,7′-diol (SPINOL) based phosphoric acids is described. 6,6′-Bis(2,4,6-triisopropylphenyl)SPINOL-based phosphoric acid was found to be a general, highly enantioselective catalyst for such allylboration reactions and excellent enantioselectivities were obtained for different types of aldehydes including aromatic aldehydes, α,β-unsaturated aldehydes, propargylic aldehydes, and aliphatic aldehydes.

Room temperature nickel(II) complexes [(4-MeOC₆H₄)Ni(PCy₃)₂OTs and Ni(PCy₃)₂X₂ (X=Cl, Br)]-catalyzed cross-coupling reactions of aryl/alkenyl sulfonates with arylboronic acids are described. The nickel(II) complex (4-MeOC₆H₄)Ni(PCy₃)₂OTs proved to be a general catalyst for the Suzuki–Miyaura cross-coupling reactions of aryl sulfonates with arylboronic acids. By limiting the amount of the water in the initial catalytically active Ni(0) species generation stage, Ni(PCy₃)₂X₂ (X=Cl, Br) could also be efficient catalysts for the cross-coupling reactions a variety of aryl/activated alkenyl tosylates with arylboronic acids. The mild reaction condition, the easy availability of the catalysts and excellent coupling yields make these catalyst systems potentially useful in organic synthesis.
