The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 1111-67-7, Name is Cuprous thiocyanate, belongs to copper-catalyst compound, is a common compound. Synthetic Route of 1111-67-7In an article, once mentioned the new application about 1111-67-7.
The reaction of copper(I) salts CuX (X = Cl, Br, I, CN, SCN), [Cu(CH3CN)4]PF6 with 1-diphenylphosphino-1?-di-tert-butylphosphinoferrocene (dppdtbpf) in 1:1 M ratio in DCM-MeOH (50:50 V/V) at room temperature afforded mono and binuclear compounds having formula [Cu2(mu-Cl)2(kappa2-P,P-dppdtbpf)2] (1), [Cu2(mu-Br)2(kappa2-P,P-dppdtbpf)2] (2) [Cu2(mu-I)2(kappa2-P,P-dppdtbpf)2] (3), [Cu2(mu-CN)2(kappa2-P,P-dppdtbpf)2] (4), [Cu2(mu2-SCN)2(kappa2-P,P-dppdtbpf)2] (5), and [Cu(kappa2-P,P-dppdtbpf)(CH3CN)2]PF6 (6). Reacting palladium(II) complex [Pd(C6H5CN)2Cl2] with dppdtbpf gave mononuclear compound [Pd(kappa2-P,P-dppdtbpf)Cl2] (7). The reaction of dppdtbpf with sulfur powder under reflux in chloroform afforded a ferrocene diphosphine disulfide dppSdtbpSf (8). All of the synthesized compounds were characterized by elemental analyses, IR, 1H and 31P NMR, ESI-MS and electronic absorption spectroscopy. Molecular structures for the compounds 5, 6, 7 and 8 were determined crystallographically. Compound 5 exists as centrosymmetric dimer in which the two copper atoms are bonded to two dppdtbpf ligands and two bridging thiocyanate groups in mu2-manner. In cationic compound 6, the copper atom is coordinated to one dppdtbpf ligand in kappa2-manner and two acetonitrile molecules, whereas in 7, the palladium(II) adopted cis square-planar geometry by coordinating to one dppdtbpf ligand in kappa2-manner and two chlorine atoms. Compound 8 revealed a sandwiched structure with both phosphine groups sulfurized. The electrochemical properties of 1-6 were studied by cyclic voltammetry. Compounds 1-6 exhibited moderately weak to strong luminescence properties, however compounds 7 and 8 are non-emissive in the solution state.
