N-Functionalization of the Tetrahedrane Fe2(CO)6(μ-SNH)

Abstract

The azadiferrathia tetrahedrane, Fe2(CO)6(μ-SNH) (1), was deprotonated to give the anion [Fe2(CO)6(μ-SN)]− (2) which reacts with halides of phosphorus, arsenic, silicon, germanium, tin and boron by formation of element-nitrosen bonds. The new compounds were characterized by their IR. NMR (1H ,11B, 13C, 15N, 29Si, 31P, 119Sn)and mass spectra. The molecular structure of [Fe2(CO)6(μ-SN-SiMe2CH2-)]2 (11) was determined by X-ray structure analysis (space group P1̄; triclinic; a = 799.8(2), b = 958.5(2), c = 1035.7(2) pm, a = 86.30(2)°, α = 81.27(2)°, β = 69.90(2)°).
