Cross Coupling Reaction

An efficient protocol for one-pot deoxygenative and regioselective synthesis of 2-arylsulfonylquinolines has been developed via iron-catalysed cross-coupling reaction of quinoline N-oxides with sodium arylsulfinates in moderate to good yields under microwave irradiation. The reactions proceeded over a broad range of substrates with good regioselectivity and functional group tolerance.

The aromatic dimers play a significant role in many aspects. Herein, we report a simple palladium-carbon catalyst that is highly effective for the dimerization of brominated aromatic compounds under mild conditions using abundant brominated aromatic compounds, bis(pinacolate)diboron and potassium acetate by a ‘one-pot’ method. This process, which we believe proceeds via a Suzuki–Miyaura cross-coupling reaction mechanism, allows access to a variety of aromatic compounds under mild reaction conditions and has a good functional group tolerance with moderate to high yields.

High Yields

A novel and highly efficient dehydrogenative cross-coupling reaction between α-amino carbonyl compounds and azoles by copper catalysis using di-tert-butyl peroxide (DTBP) as an oxidant was described. A diverse range of azoles underwent the dehydrogenative imidoylation smoothly with various α-amino carbonyl compounds for the exclusive formation of the corresponding N-imidoyl azoles in high yields under air. The synthetic method has the advantages of good functional-group tolerance, wide substrate scope, excellent yields and simple operation, thus providing a convenient and practical protocol for the synthesis of various functionalized azoles.

We report a direct cross-coupling reaction between (het)aryl pivalates/tosylates and di(het)arylzinc species in 2-methyltetrahydrofuran/ N-methyl pyrrolidone (1:1), which occurs via C–O bond cleavage under microwave irradiation. The reaction takes place smoothly in short reaction times without the addition of any catalyst or ligand. The reaction is suitable for a broad scope of substrates and exhibits good functional group compatibility, utilizes a simple work-up procedure, and gives the desired products in high purity.

AbstractAn efficient protocol for the synthesis of 2-arylsulfonyl quinolines has been developed via a metal-free catalyzed cross-coupling reaction of chloroquinoline with sodium arylsulfinates in moderate-to-good yields under microwave irradiation. The reactions proceed with a wide range of substrates with good functional group tolerance.

Palladium Catalyzed

The decarboxylation of benzyl fluorobenzoates has been developed by using the palladium catalyst prepared in situ from Pd(η3-allyl)Cp and bulky monophosphine ligand XPhos. The catalytic reaction afforded a range of fluorinated diarylmethanes in good yields with broad functional-group compatibility. The substrates were readily synthesized by condensation of the corresponding benzoic acid with benzyl alcohol. Therefore, the transformation is formally regarded as a cross-coupling reaction between fluorine-containing benzoic acids and benzyl alcohols.
