Final Thoughts on Chemistry for 19845-69-3

Application of 19845-69-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 19845-69-3, Name is 1,6-Bis(diphenylphosphino)hexane, molecular formula is C30H32P2. In a Article£¬once mentioned of 19845-69-3

Uptake of a Hg or Hg2 unit into the center of cage-type platinum clusters supported by diphosphines having long methylene carbon chains: X-ray structure of *2C6H6 (dpphex = 1,6-bis(diphenylphosphino)hexane, R = 2,6-dimethylphenyl)

When Pt(COD)Cl2 was treated with sodium amalgam in the presence of aromatic isocyanide (RNC, R = 2,6-Me2C6H3 (Xyl) or 2,4,6-Me3C6H2 (Mes)) and diphosphine with long methylene chain (diphos = Ph2P(CH2)nPPh2, n = 5 (dpppn) or 6 (dpphex)), two kinds of Hg-Pt mixed metal clusters, (2) and (3), were obtained.The structure of 3b (R = Xyl, diphos = dpphex) was determined by an X-ray analysis to be a cage-type cluster where a Hg2 unit was incorporated into a trigonal-anti-prismatic platinum core, two Pt3 triangles being supported by three dpphex ligands (close-type).The cluster 2 was assumed to have an incomplete cage-type structure (open-type), and was converted to close-type 3 by treatment with an equivalent diphosphine ligand.When dppb (n = 4) was used, an open-type mixed metal cluster in which one mercury atom was captured, (4), was obtained as the sole product.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 19845-69-3 is helpful to your research., Application of 19845-69-3
