Dabco as an inexpensive and highly efficient ligand for palladium-catalyzed Suzuki-Miyaura cross-coupling reaction.
نویسندگان
چکیده
An inexpensive and highly efficient Pd(OAc)(2)/Dabco catalytic system has been developed for the cross-coupling of aryl halides with arylboronic acids. A combination of Pd(OAc)(2) and Dabco (triethylenediamine) was observed to form an excellent catalyst, which affords high TONs (turnover numbers; TONs up to 950 000 for the reaction of PhI and p-chlorophenylboronic acid) for Suzuki-Miyaura cross-coupling of various aryl iodides and bromides with arylboronic acids.

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 ...

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...
