New cyclopalladated benzothiophenes: a catalyst precursor for the Suzuki coupling of deactivated aryl chlorides.
Dimeric benzothiophene-based palladacycles were synthesized from thioanisole-substituted perfluoroalkyl propargyl imines and palladium(II) salts via an intramolecular thiopalladation pathway. The treatment of benzothiophene-based palladacycles with an excess of phosphine ligands in benzene at room temperature selectively afforded trans-bis(phosphine) palladium complexes in good yields. The tran...
متن کاملTriazole-based monophosphine ligands for palladium-catalyzed cross-coupling reactions of aryl chlorides.
A variety of triazole-based monophosphines (ClickPhos) have been prepared via efficient 1,3-dipolar cycloaddition of readily available azides and acetylenes. Their palladium complexes provided excellent yields in the amination reactions and Suzuki-Miyaura coupling reactions of unactivated aryl chlorides. Ligand 7i, which has a 2,6-dimethoxybenzene moiety, provided good results in Suzuki-Miyaura...
متن کامل[2.2]Paracyclophane-based monophosphine ligand for palladium-catalyzed cross-coupling reactions of aryl chlorides.
A new [2.2]paracyclophane-based electron-rich and sterically bulky monophosphine ligand has been synthesized by an efficient and straightforward method. When combined with palladium, this ligand shows excellent performance in the Buchwald-Hartwig amination and Suzuki-Miyaura coupling reactions of various aryl chlorides. In both types of reactions, ortho-substituted, deactivated aryl chlorides a...
متن کاملCatalytic direct cross-coupling of organolithium compounds with aryl chlorides.
Palladium-catalyzed direct cross-coupling of aryl chlorides with a wide range of (hetero)aryl lithium compounds is reported. The use of Pd-PEPPSI-IPent or Pd2(dba)3/XPhos as the catalyst allows for the preparation of biaryl and heterobiaryl compounds in high yields under mild conditions (room temperature to 40 °C) with short reaction times.
