Application of 246047-72-3, An article , which mentions 246047-72-3, molecular formula is C46H65Cl2N2PRu. The compound – (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium played an important role in people’s production and life.
Chelated tethering ligands were confined on a Au(111) substrate, and the confinement of the ligands was confirmed by X-ray photoelectron spectroscopy (XPS). Palladium was anchored to the ligands to construct heterogeneous (Pd)-L-Au(111) catalysts (L = ligand). A (Pd)-Au(111) catalyst was also prepared by adsorbing the Pd complex directly on the Au(111) substrate without a tethering ligand. Both types of catalysts were used in the Mizoroki-Heck reaction to evaluate their catalytic activities. The tether-ligated Pd catalyst (Pd)-L-Au(111) activity decreased with recycling, whereas the (Pd)-Au(111) catalyst was quite stable upon reuse. The surfaces of both catalyst types were evaluated using XPS to determine the presence of tethering ligands and/or Pd on the Au(111). The ligands of the tether-ligated Pd catalysts could not be detected on the Au(111) surface after the Mizoroki-Heck reaction, which suggests weak bonding of the S-Au by which the ligand is bound to the Au(111) substrate.
