Ferrocenyl hydroxymethylphosphines (η5-C5H5)Fe[η5-C5H4P(CH2OH)2] and 1,1′-[Fe{η5-C5H4P(CH2OH)2}2] and their chalcogenide derivatives
摘要:
The ferrocenyl hydroxymethylphosphines FcP(CH2OH)(2) [Fc = (eta(5)-C5H5)Fe(eta(5)-C5H4)] and 1,1'-Fc'[P(CH2OH)(2)](2) [Fc' = Fe(eta(5)- C5H4)(2)] were prepared by reactions of the corresponding primary phosphines FcPH(2) and 1,1'-Fc'(PH2)(2) with excess aqueous formaldehyde. The crystal structure of FcP(CH2OH)(2) was determined and compared with the known ferrocenyl hydroxymethylphosphine FcCH(2)P(CH2OH)(2). The chalcogenide derivatives FcP(E)(CH2OH)(2) and 1,1'-Fc'[P(E)(CH2OH)(2)](2) (E = O, S, Se) were prepared and fully characterised. Crystal structure determinations on FcP(O)(CH2OH)(2) and FcP(S)(CH2OH)(2) were performed, and the hydrogen-bonding patterns are compared with related compounds. The sulfide shows no hydrogen-bonding involving the phosphine sulfide group, in contrast to other reported ferrocenyl hydroxymethylphosphine sulfides. The platinum complex cis-[PtCl2{FcP(CH2OH)(2)}(2)] was prepared by reaction of 2 mol equivalents of FcP(CH2OH)(2) with [PtCl2(1,5-cyclo-octadiene)], and was characterised by P-31-NMR spectroscopy and negative ion electrospray mass spectrometry, which gave a strong [M+Cl](-) ion.
