The Reaction of Cpru(Pph3)2+ with Organic Thiols - Synthesis and Characterization of [Cpru(Pph3)2(Rsh)]Bf4 (R = Benzyl, Phenethyl) and the Molecular and Crystal-Structure of [Cpru(Pph3)2(C6h5ch2ch2sh)]Bf4.Ch2cl2

The isolation and characterization of two mercaptan complexes of the general formula [CpRu(PPh3)2(RSH)]BF4, where R = benzyl and phenethyl, were undertaken to model the substrate/catalyst interaction of the hydrodesulfurization (HDS) process. The IR data show a shift in the S-H stretching frequency upon coordination. The structure of the [CpRu(PPh3)2(C6H5CH2CH2SH)]BF4 complex was determined by X-ray diffraction techniques: monoclinic space group P2(1/n,) a = 15.317(4), b = 13.924(9), c = 21.815(7) angstrom, beta = 95.20(2)-degrees, Z = 4, R = 0.057, R(w) = 0.073. The Ru is attached to two triphenylphosphine ligands, a clopentadienyl and the phenethylmercaptan. The Ru-S distance is 2.369(2) angstrom and the S-H distance is 1.18 angstrom.
