suzuki-miyaura cross-coupling reaction catalyzed using highly efficient cn-dimeric ortho-palladated complex under microwave irradiation and conventional heating
نویسندگان
چکیده
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 the reactions and reduced the reaction times some extent in comparison with traditional heating conditions.

متن کاملSynthesis of functionalized aryl-alkenes catalyzed by CN-ortho-palladated complex of 2,3-dimethoxybenzaldehyde oxime under microwave irradiation
A new dimeric orthopalladated complex was synthesized via reaction of 2,3-dimethoxy benzaldehyde oxime with palladium chloride and lithium chloride in methanol as solvent and sodium acetate as base at room temperature. The catalytic activity of this dimeric [Pd{C6H2(-CH=NOH)-(OMe)2-2,3}(µ-Cl)]2 complex as an efficient, air, and moisture tolerant catalyst was investigated in Mizoroki–Heck cross ...

The catalytic acvtivity of dimeric and monomeric ortho-palladated complexes [Pd{C6H2(CH2NH2-(OMe)2,3,4}(µ-Cl)]2)2) and [Pd{C6H2(CH2NH2-(OMe)2,3,4}Cl(PPh3)](3), was investigated in Heck cross-coupling reaction. These complexes are more active and efficient catalysts for Heck cross-coupling reaction. The palladium complexes 2 and 3 is employed in the Heck cross-coupling reaction between styrene a...
متن کاملDabco as an inexpensive and highly efficient ligand for palladium-catalyzed Suzuki-Miyaura cross-coupling reaction.
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...
