  摘要：

  Interesting differences have been observed in the reactivity of mer-[FeH(CO)(3){Si(OMe)(3)}{Ph(2)PCH(2)C(O)Ph}] and mer-[FeH(CO)(3){Si(OMe)(3)}{Ph(2)PCH(2)C(O)NPh(2)}] toward tin derivatives of the type [SnX(2)R(2)]. Whereas the former which contains a diphenylphosphino ketone ligand reacted with [SnCl(2)Bu(2)(n)], [SnBr(2)Bu(2)(n)], [Sn(O(2)CMe)(2)Bu(2)(n)] or [SnCl(2)Ph(2)] to yield only one type of complex [(OC)(3){(MeO)(3)Si}-Fe{mu-Ph(2)PCH=C(O)Ph}SnR(2)] (R = Bu(n) or Ph), respectively, the latter with the (N) over bar,N-diphenyl-2-diphenylphosphinoacetamide ligand afforded different products depending upon the nature of X in [SnX(2)Bu(2)(n)]. With [SnCl(2)Bu(2)(n)] or [SnBr(2)Bu(2)(n)] the product obtained was [(OC)(3){(MeO)(3)Si}-Fe{mu-Ph(2)PCH=C(O)NPh(2)}SnBu(2)(n)], but with [Sn(O(2)CMe)(2)Bu(2)(n)] no reaction was observed. The halides appear to be better leaving groups than acetate and this, associated with the different acidity of the PCH2 protons between the two phosphine ligands, is responsible for the formation or not of the six-membered ring (Fe-Sn-phosphinoenolate) complex the stability of which constitutes the driving force in the reaction.
