文摘

Two novel asymmetric azo-aliphatic compounds [(CH₃)₃CN=NC(S(CH₂)_nS)C(O)CH₃, n = 2 (5) andn = 3 (6)] have been synthesized via a tandem procedure. The reaction of 5 and 6 with Fe₂(CO)₉ affordsthree novel dinuclear iron complexes displaying C-S bond activation (5b, 5c, and 6c). 5b and 5c exhibitan unusual stereochemistry about the Fe₂ unit, as revealed by X-ray diffraction analyses. Additionally,two alquildithiolate-bridged iron hexacarbonyl complexes (5a and 6a) were obtained as a result of adouble C-S bond activation from 5 and 6, respectively. The structures of 5, 5b, and 5c were fullyestablished by X-ray diffraction analyses.
