copper-catalyzed directarylation. Readily available and structurally simple aryl precursors such as arylboronicacids, aryl trialkoxysilanes and dimethyl-aryl-sulfonium salts were used as the source for the aryl substituents. The scope of the reactions was tested, and the reactions were insensitive to the electronic nature of the aryl groups, as both electron-rich and electron-deficient aryls were successfully

transformations of CF3 group with nitro compounds into amides or Schiff bases employing Ytterbia as a catalyst. This process proceeds via C−F bond activation, accompanied with utilisation of Si-based reductants/oxygen scavengers – reductants of the nitro group. The scope and limitations of the disclosed methodologies are thoroughly studied. To the best of our knowledge, this work is the first example of

functionalization, directing‐group strategy was developed for the improvement of chemical reactivity and selectivity. Recently, to avoid the inherent limitations of traditional mono‐role directinggroups, a dual‐role oxidizing‐directing‐group strategy was developed, in which the directinggroup acts both as directinggroup and oxidant. Herein, we report a multiroledirectinggroup, which possesses multiple
