Extracurricular laboratory:new discovery of 32993-05-8

Reference of 32993-05-8, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a patent, introducing its new discovery.

Cyclopentadienyl-Ruthenium and -Osmium Chemistry. XXII. Synthesis, X-Ray Structure and Some Reactions of RuCl(PPh3)(eta1-Ph2PCH2PPh2)(eta-C5H5), Containing a Monodentate CH2(PPh2)2 Ligand

Stoichiometric amounts of RuCl(PPh3)2(eta-C5H5) and dppm react in refluxing C6H6 to give RuCl(PPh3)(eta1-dppm)(eta-C5H5), which has been fully characterized by an X-ray study (triclinic, space group P<*>, a 22.377(6), b 9.913(2), c 9.826(3) Angstroem, alpha 70.46(2), beta 78.72(2), gamma 80.40(2) deg, Z 2) in which 3299 data were refined to R 0.046, R’ 0.052.Structural parameters are similar to those of other RuX(PR3)2(eta-C5H5) complexes.The chloro complex was converted was converted into + salts; the other PPh3 ligand can be replaced by a second dppm ligand to give +, which contains both mono- and bidentate dppm ligands.Alkylation of the uncoordinated phosphorus with Mel is accompanied by halogen exchange to give I, while reactions with a variety of transition metal complexes result in abstraction of PPh3 and formation of RuCl(dppm)(eta-C5H5).
