the first time allows the decarboxylative cross‐coupling of aryl and acyl carboxylates with aryl triflates. In contrast to aryl halides, these electrophiles give rise to non‐coordinating anions as byproducts, which do not interfere with the decarboxylation step that leads to the generation of the carbon nucleophilic cross‐coupling partner. As a result, the scope of carboxylate substrates usable in this

10-phenanthroline, PdI2, and Tol-BINAP, for the first time allows the decarboxylative coupling of carboxylic acids with aryl triflates. In contrast to previous decarboxylative couplings that remained limited to certain activated carboxylates, e.g., ortho-substituted benzoates, this halide-free protocol is generally applicable to aromatic carboxylic acid salts regardless of their substitution pattern.

Palladium-catalyzed Suzuki–Miyaurareaction is an important synthetic strategy for the synthesis of biaryl compounds. This work describes that palladiumcomplexes with N,O-bidentate ligands bearing N-oxide units from cyclic secondary amines were used as highly efficient catalysts for Suzuki–Miyaurareactions of aryl halides with arylboronic acids. The reaction exhibited good functional group compatibility
