In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1111-67-7, name is Cuprous thiocyanate, introducing its new discovery. category: copper-catalyst
Syntheses and crystal structures of
Through the reaction of CuSCN with AsPh-(SiMe3)2 in the presence of tertiary phosphines the compounds [Cu4(As4Ph4)2(PRR? 2)4] (1-3) (1: R = R? = nPr, 2: R = R? = Et; 3: R = Me, R? = nPr) and [Cu14(AsPh)6(SCN)2-(PEt2Ph) 8] (4) can be synthesised. Using CuCl instead of CuSCN results to the cluster complexes [Cu14(AsPh)6Cl2(PRR?2) 8] (5-6) (5: R = R? = Et; 6: R = Me, R? = nPr), [Cu12(AsPh)6(PPh3)6] (7) and [Cu10(AsPh)4Cl2-(PMe3)8] (8). Through reactions of CuOAc with As(SiMe3)3 in the presence of tertiary phosphines the compounds [Cu12(AsSiMe3)6(PRR?2) 6] (9-11) (9: R = R? = Et; 10: R = Ph, R? = Et; 11: R = Et, R? = Ph) and [Cu8(AsSiMe3)4-(PtBu 3)4] (12) can be obtained. In each case the products were characterised by single-crystal-X-ray-structure-analyses. As the main structure element 1-3 each have two As4Ph42-chains as ligands. In contrast 4-12 contain discrete AsR2–ligands. WILEY-VCH Verlag GmbH, 2001.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1111-67-7, and how the biochemistry of the body works.category: copper-catalyst
