lithium amide in liquidammonia. The transition metal phosphane complex (R2N)2(H2N)PNi(CO)3 (3) was prepared by reaction of 2a with tetracarbonylnickel. N-Complexation of 2a with trimethylalane affords the iminophosphorane-alane adduct (R2N)2HP=N(H)AlMe3 (4) by 1,2-H shift from the nitrogen to the phosphorus atom. The corresponding reaction with aluminium trichloride leads to the formation of the salt
KHFe(CO)4 reacts with tris(amino)phosphines by substitution at phosphorus leading to [bis(amino)phosphine]tetracarbonyliron complexes [(R1R2N)2PH]Fe(CO)4. The X-ray structure has been determined for R1=R2=Ph. Deprotonation of these complexes with KH affords stable potassium phosphidotetracarbonylferrates which can be alkylated or acylated at phosphorus.
KHFe(CO)4通过在磷处取代而与三(氨基)膦反应,生成[双(氨基)膦]四羰基铁配合物[(R 1 R 2 N)2 PH] Fe(CO)4。已经针对R 1= R 2= Ph确定了X射线结构。用KH使这些配合物去质子化,得到稳定的磷酸四羰基高铁酸钾,其可在磷处被烷基化或酰化。
