[source] Bis(imino)pyridine palladium(II) complexes as efficient catalysts for the Suzuki,Miyaura reaction in waterAPPLIED ORGANOMETALLIC CHEMISTRY, Issue 2 2010Ping Liu Abstract Bis(imino)pyridine palladium(II) complexes 3 and 4 of type [PdCl(L)PF6] are found to be efficient catalysts for Suzuki,Miyaura reactions of aryl halides and arylboronic acids. The reactions proceed smoothly to generate the corresponding biaryl compounds in moderate to excellent yields. The synthesis of various fluorinated biphenyl derivatives was successfully achieved by the complex 4 catalyzed the Suzuki,Miyaura reaction in the presence of surfactants bearing a long alkyl chain.

The Pd,L1 and Pd,L2 complexes offer exceptionally high activity in Suzuki,Miyaura cross-couplings of aryl chlorides. The extremely congested synthesis of tetra- ortho -substituted biaryl compounds is achieved for the first time by simply using triarylphosphane ligands. [source] | ||||||||||
