The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1,2-Bis(diphenylphosphino)ethane( cas:1663-45-2 ) is researched.Application of 1663-45-2.Faujdar, Hemlata; Spannenberg, Anke; Kaur-Ghumaan, Sandeep published the article 《Structural and HER studies of diphosphine-monothiolate complexes [Fe2(CO)4(μ-naphthalene-2-thiolate)2(μ-dppe)] and [Fe2(CO)4(μ-naphthalene-2-thiolate)2(μ-DPEPhos)]》 about this compound( cas:1663-45-2 ) in Inorganica Chimica Acta. Keywords: iron diphosphine thiolate complex preparation crystal structure cyclic voltammetry; hydrogen evolution reaction catalyst iron diphosphine thiolate complex. Let’s learn more about this compound (cas:1663-45-2).
Two new compounds [Fe2(CO)4(μ-naphthalene-2-thiolate)2(μ-dppe)] 1 and [Fe2(CO)4(μ-naphthalene-2-thiolate)2(μ-DPEPhos)] 2 with chelating phosphine ligands were synthesized and characterized {dppe = 1,2-Bis(diphenylphosphino)ethane and DPEPhos = (Oxydi-2, 1-phenylene)bis(diphenylphosphine)}. The bridging coordination mode of the diphosphine ligand in complex 1 was confirmed by x-ray crystallog. Complexes 1 and 2 were further evaluated as catalysts for the hydrogen evolution reaction (HER) by electrochem. studies. Complex 1 showed better stability whereas complex 2 degraded in the presence of acids.
As far as I know, this compound(1663-45-2)Application of 1663-45-2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
