Copper(i)-catalyzed sulfonylative Suzuki-Miyaura cross-coupling.
نویسندگان
چکیده
Using a simple copper(i) catalyst has allowed a high yielding sulfonylative-Suzuki-Miyaura cross-coupling reaction to be developed. The process provides a single step route to diaryl sulfones from the direct combination of aryl boronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide is delivered from the surrogate reagent, DABSO. Variation of the reaction conditions allowed interruption of the sulfonylative-Suzuki coupling, resulting in the formation of a presumed Cu-sulfinate intermediate. These sulfinates could be trapped as their sodium salts and treated with electrophiles to allow access to arylalkyl sulfones, β-hydroxyl sulfones, sulfonamides and sulfonyl fluorides.

Suzuki-Miyaura cross-coupling reaction catalyzed using highly efficient CN-dimeric ortho-palladated complex under microwave irradiation and conventional heating
Suzuki cross-coupling reaction of different aryl halides with arylboronic acids was successfully carried out in methanol using ortho-palladated complex of 2-methoxyphenethylamine. All substrates afforded the corresponding products in good to high yields in the presence of low amounts of this complex as efficient and active catalyst. Application of microwave irradiation improved the yields of th...

متن کاملPalladium Loaded on Magnetic Nanoparticles as Efficient and Recyclable Catalyst for the Suzuki- Miyaura Reaction
Palladium is the best metal catalyst for Suzuki cross coupling reaction for synthesize of unsymmetrical biaryl compounds. But its high cost limits its application in wide scale. Using of nanoscale particles as active catalytic cites is a good approach for reducing needed noble metal. By loading precious nanoparticles on magnetic nanocores as a support, recycling and reusing of catalyst will be ...
متن کاملAn air stable and efficient palladium catalyst for Suzuki-Miyaura cross coupling reaction at room temperature
The cross-coupling reaction between phenylboronic acid and various types of aryl halides (Suzuki reaction) was carried out using a catalytic amount of a new palladium catalyst (1-benzyl-3-(1-benzyl-1-methylpyrrolidin-1-ium-2-yl) pyridin-1-ium palladium chloride [DBNT][PdCl4]) in poly (ethylene glycol) (PEG-200) in the presence of KOH as the base. This new catalyst was synthesized and...
