A defined N-heterocyclic carbene complex for the palladium-catalyzed Suzuki cross-coupling of aryl chlorides at ambient temperatures

Highly active but sterically demanding: Ambient-temperature Suzuki cross-coupling of aryl chlorides is possible with a palladium(o) complex bearing two bulky, N-heterocyclic carbene ligands (see structure). Nearly quantitative yields are obtained within two hours with some reagents, which makes this compound the most active catalyst known to date under these conditions.

Palladium(II) coordination complexes of nine 3- or 5-arylpyrazoles (phenyl, 2-bromophenyl, or 3-methoxyphenyl), as well as of 3,5-diphenylpyrazole, are reported.A cis-trans mixture of isomers is found in the case of 3-aryl-1-methylpyrazoles, the cis-isomers being transformed into trans by heating.Only trans isomers are isolated with the other ligands.Cyclopalladation of 3-aryl-1-methylpyrazoles can be performed with palladium(II) acetate, and the resultant mu-acetate bridged dimers can be transformed into mu-chloro bridged dimers or acetylacetonate monomers.The structures of the complexes have been characterized by 1H- and 13C-NMR spectroscopy.

Synthesis of biphenyl-based arsine ligands by Suzuki-Miyaura coupling and their application to Pd-catalyzed arsination

A versatile and efficient approach for the synthesis of new biphenyl-based arsine ligands, by a Pd-catalyzed arsination to introduce the -AsPh2 moiety, and then a Suzuki-Miyaura cross-coupling for biaryl construction is reported. By Pd-catalyzed arsination with n-Bu3SnAsPh2 (1), (2-bromophenyl)diphenylarsine (2, 83%) was obtained. The Suzuki-Miyaura reaction between the bromoarsine 2 and aryl boronic acids bearing different substituents provided biarylarsine ligands (80-99%). The efficiency of catalysts derived from the new biarylarsine ligands was evaluated in the Pd-catalyzed arsination with perfluoroalkyl iodides (RfI). Outstanding activities of catalysts derived from Pd/methoxybiarylarsine ligands were found in this coupling reaction affording perfluoroalkyl arsines in very good yields (57-100%).
