Synthesis and catalytic activity of chiral linker-bridged bis-N-heterocyclic carbene dipalladium complexes

A series of new chiral-bridged N-heterocyclic carbene ligands with different substituents and their corresponding palladium complexes have been synthesised. The effect of the substituents on the catalytic activity of these Pd complexes was investigated in the Suzuki reaction of p-bromotoluene with phenylboronic acid, and the results showed that the complexes with aryl substituents performed better than those with alkyl substituents. The complex with the most sterically hindered substituent (diisopropyl on a phenyl group) performed best, and it was also an efficient catalyst for the reaction of various arylboronic acids with aryl halides having different electronic and steric properties. In addition, it was employed as a catalyst in the asymmetric Suzuki reaction, but only moderate yields of 1,1-binaphthalenes with less than 20% enantiomeric excess were obtained.

Synthesis and characterization of novel chiral NHC-palladium complexes and their application in copper-free Sonogashira reactions

A new series of chiral N-heterocyclic carbene (NHC) palladium complexes were synthesized from a relatively inexpensive amino acid, l-phenylalanine. All these compounds were fully characterized by 1H-NMR, 13C-NMR and elemental analysis. The X-ray molecular structures of two of the complexes were reported. The catalytic activity of the four palladium complexes was successfully tested in the Sonogashira reaction under copper free conditions in air. The palladium complex 3a provided good activity in the Sonogashira coupling reaction. The Royal Society of Chemistry 2012.

Photoinduced electron-transfer reactions of tri-1-naphthyl phosphate and di-1-naphthyl methylphosphonate sensitised by 9,10-dicyanoanthracene

1,1′-Binaphthyl is formed by photoinduced electron-transfer reactions of tri-1-naphthyl phosphate and di-1-naphthyl methylphosphonate sensitised by 9,10-dicyanoanthracene in MeCN, while no reaction occurs in the case of mono-1-naphthyl and di- or tri-phenyl esters.
