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

A bimetallic copper/palladium catalyst system is disclosed that enables the use of tosylates as carbon electrophiles in decarboxylative coupling reactions. A variety of aromaticcarboxylatesalts, regardless of their substitution pattern, have been coupled with these inexpensive and readily available electrophiles to give the corresponding biaryl compounds in good yields (see scheme).

catalyst system is presented that enables the decarboxylative cross‐coupling of triflates with carboxylate salts at only 100 °C, which is 70 °C lower than with previous Cu/Pd‐based systems. The new protocol allows the coupling of a broad range of aryl triflates with various substituted 2‐nitrobenzoates in good to excellent yields. The key feature of the catalyst system is a bidentate P,N‐ligand designed

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
