The occurrence of direct transmetalation between gold(III) and boron species during gold-catalyzed cross-coupling reactions has recently become the subject of intense discussion. In this work, we investigate the transmetalation reaction between discrete, stable gold(III) complexes and boron reagents. Interestingly, electron-rich arylboronic acids remain unreactive under neutral conditions, whereas
A porous superacid material with a high surface area and abundant accessible active sites is rationally designed, showing outstanding catalytic activities and durability in industrial chemical transformations.
The almost quantitative synthesis of homologous luminescent fluorophosphoranes, by SNAr cyclization of (2′-F,2-(PR2)biaryl) phosphines made from easily accessible reagents, is reported and the DFT cyclization mechanism and alternative pathways to complete this isomerization are studied and discussed.

Mild and Efficient Ni-Catalyzed Biaryl Synthesis with Polyfluoroaryl Magnesium Species: Verification of the Arrest State, Uncovering the Hidden Competitive Second Transmetalation and Ligand-Accelerated Highly Selective Monoarylation
Employing a nickel catalyst and electron-deficient polyfluoroaryl magnesium species, a highlyselectivemonoarylation of polyfluoroarenes containing multiple identical coupling sites has been achieved for the first time, which represents a long-standing problem due to the competitive reactivity between the desired products and the starting polyfluoroarenes. Because of the negative fluorine effect,
