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., Synthetic Route of 19845-69-3
Synthetic Route 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
Treatment of a dichloromethane solution of the salt 2 with two equivalents of the complex PF6 (M=Cu or Ag) at -30 deg C, followed by the addition of one equivalent of PH2p(CH2)nPPh2 (n=1-6) affords the mixed-metal cluster compounds (CO)12> in ca. 65-75percent yield.These species have been characretized by i.r. and n.m.r. spectroscopy and the structures of (CO)12) (n=2,3, or 5) have been determined by X-ray difraction studies.The clusters all adopt the same metal core strcuture, which consist of a tetrahedron of ruthenium atoms capped by a Group 1B metal, with one of the MRu2 faces of the MRu3 tetrahedron so formed further capped by a second Group 1B metal to give a capped trigonal-bipyramidal skeleton geometry.The other two MRu2 faces of the MRu3 tetrahedron are each capped by a triply-binding hydrido ligand, the bidentane diphosphine ligand bridges the two coinage metals, and each ruthenium atom is ligated by three terminal CO groups.Variable-temperature 1H and 31P-<1H> n.m.r. studies show that, at ambient temperature in solution, the metal frameworks of all of the cluster still undergo dynamic behaviour involving coinage metal site-exchange, even though the two Group 1B metals are linked together by bidentane diphosphine ligands.
