12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2, belongs to chiral-phosphine-ligands compound, is a common compound. In a patnet, once mentioned the new application about 12150-46-8, category: chiral-phosphine-ligands
New compounds Ia-h of the form [(Me2SO)ClPt(HR2DTO kappa-S,S Pt)] (HR2DTO = secondary dithiooxamide, with R = methyl, ethyl, n-propyl, n-butyl, n-decyl, isopropyl, (R)-1-phenylethyl, or (S)-2-hydroxypropyl; kappa-S,S Pt denotes the coordination of the DTO moiety to the Pt atom) have been prepared and used to synthesize platinum(II)/ferrocene dimetallic species IIa-h of formula [(dppf)Pt(HR2DTO kappa-S,S Pt)]Cl (dppf = 1,1?-diphosphinoferrocene). Complexes IIa-e, bearing unbranched groups on the dithiooxamide moiety (i.e., R = methyl, ethyl, n-propyl, n-butyl, or n-decyl groups), self-assemble upon standing to form unprecedented hexameric macrocycles IIIa-e. Compounds IIa-e, IIIa-e, as well as IIf-h, have been characterized by a combination of 1H, 13C, 31P NMR spectroscopy and 2D-ROESY and diffusion-ordered NMR spectroscopy (DOSY) experiments; the latter experiments have been used to calculate the hydrodynamic radius of IIa-e and IIIa-e, assisted by the data provided by the X-ray crystal structure of IIh. Compounds IIIa-e are characterized by the presence of six dppf bridging units occupying the inner rim of the macrocycles and exhibit interesting properties, for example, oxidation of IIIa-e occurs around +0.40 V versus saturated calomel electrode (SCE), whereas oxidation of the type II species occurs at potentials greater than +1.0 V. Oxidation of IIIa-e is explained through a delocalized orbital extending over the six dppf subunits. The reversibility of the self-assembly process is finally demonstrated by alternate addition of acids and bases to the type III compounds. Dimetallic building blocks containing PtII dithiooxamide and ferrocene subunits self-assemble in solution to generate unprecedented hexameric macrocycles that have peculiar geometrical, spectroscopic, redox, and reactivity properties. The self-assembly process is reversible and can be repeated at will by alternating suitable inputs.
