12150-46-8. Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene,introducing its new discovery.
Gold(I) macrocycles and [2]catenanes containing sulfone-functionalised diacetylide ligands
The reaction of the polymeric digold(I) diacetylide [(AuCCCH2OC6H4)2 SO2]n with diphosphane ligands PP leads to the formation of either macrocyclic ring complexes [(AuCCCH2OC6H4)2 SO2(mu-PP)] or [2]catenanes [(AuCCCH2OC6H4)2 SO2(mu-PP)]2 by a self-assembly process. With the diphosphane ligands Ph2PCCPPh2, [Fe(C5H4PPh2)2 and Ph2P(CH2)nPPh2 (n = 4, 5 and 6), macrocyclic ring complexes result, but with the diphosphane ligand Ph2P(CH2)3PPh2, the [2]catenane selectively crystallises from an isomeric mixture of products.
