Application of 12150-46-8. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene
The known complexes [Cp2Fe2(mu-SEt)2(MeCN)2](PF6)2 (1) and Cp2Fe2(mu-SEt)2(CN)2 (2) are prepared to investigate their reactivity. The reaction of complex 2 with equimolar amounts of MeOTf yields a monomethylation product [Cp2Fe2(mu-SEt)2(CN)(CNMe)](OTf) (3). Dimethylation of complex 2 by 2 equiv. MeOTf gives a complex [Cp2Fe2(mu-SEt)2(CNMe)2](OTf)2 (4). Complex 1 containing two labile MeCN ligands reacts with several bidentate phosphine ligands, such as dppm, dppa, and dppf, to afford complexes [Cp2Fe2(mu-SEt)2(dppm)](PF6)2 (5), [Cp2Fe2(mu-SEt)2(dppa)](PF6)2 (6), and [Cp2Fe2(mu-SEt)2(dppf)](PF6)2 (7), respectively. The spectroscopic, electrochemical, and reactivity studies of iron-sulfur core complexes are performed. The structures of complexes 1-7 were confirmed by X-ray crystallography.
