Reference of 12150-46-8, 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.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a patent, introducing its new discovery.
Synthesis and Reactions of But-2-yne Complexes of Tungsten(II) containing Pyridine-2-thionate (SC5H4N): Crystal Structure of
The complex *0.5CH2Cl2 reacted with an equimolar amount of K (SC5H4N = pyridine-2-thionate) to give 1.Two equivalents of K yielded the mono(but-2-yne) complex 2.Complex 1 reacted with a slight excess of Na in acetonitrile to afford the cationic bis(but-2-yne) complex 3 which has been crystallographically characterised: monoclinic, space group P21/n, Z = 4, a = 19.806(21), b = 13.498(13), c = 15.289(13) Angstroem, and beta = 117.4(1) deg.The structure was refined to R = 0.064 for 2102 reflections above background.The coordination geometry about the tungsten may be considered to be octahedral, with the nitrogen and sulfur atoms of the pyridine-2-thionate ligand and the two cis and parallel but-2-yne ligands occupying the equatorial sites with the carbonyl and acetonitrile ligands in the axial sites.The reaction chemistry of 3 with neutral mono- and bi-dentate donor ligands is discussed.The barrier to but-2-yne rotation of several of the complexes was investigated by variable-temperature 1H NMR spectroscopy, and 13C NMR spectroscopy was used to suggest the number of electrons donated by the but-2-yne ligands to the tungsten in these complexes.
