In an article, published in an article, once mentioned the application of 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene,molecular formula is C34H28FeP2, is a conventional compound. this article was the specific content is as follows.Application In Synthesis of 1,1-Bis(diphenylphosphino)ferrocene
Synthesis, single crystal X-ray structure determination and NMR studies of Cp2Fe(PPh2)2PtPh2 and Cp2Fe(PPh2)2PtI2
Diphenyl[1,1?-bis(diphenylphosphino)ferrocene]platinum(II), Cp2Fe(PPh2)2PtPh2 (1) and diiodo[1,1?-bis(diphenylphosphino)ferrocene]platinum(II), Cp2Fe(PPh2)2PtI2 (2) were synthesized in nearly quantitative yield, with excellent purity by allowing Cp2Fe(PPh2)2 to react with (COD)PtPh2 and (COD)PtI2 (COD=1,5-cyclooctadiene), respectively. Compounds 1 and 2 have been well characterized by various analytical and spectroscopic techniques and also by single crystal X-ray diffraction. Platinum in both the complexes seemed to have a distorted square planar geometry. Interestingly, the respective bite angles (P-Pt-P bond angle) in 1 (101.2(1) A) and 2 (100.6(1) A) deviate from the ideal 90 situation and are larger than in the reported structure, dppfPtCl2 [dppf=1,1?-bis(diphenylphosphino)ferrocene]. A detailed NMR study, including 2D and simulation experiments has been performed on these compounds for complete structural assignment. The compounds 1 and 2 crystallized in triclinic space groups P1 and P1 with a=12.268(2) A, 10.089 (1); b=13.043(2) A, 10.856 (1); c=13.649(1), 17.787(1) A; alpha=100.49(1), 86.75(1); beta=93.12(1), 77.52(1); gamma=103.44(1), 64.91(1); V=2078.0(5), 1721.3(3) A3 and Z=2 and 2, respectively. The final refinements of 1 and 2 converged at R=0.0388 and 0.0580, respectively.
