摘要: Abstract The complexes [(μ-η 2 -ROC(1)S)Fe (CO) 6 (μ-SMe)] ( 1 ), undergo selective replacement of one CO by P(OMe) 3 (L ) or t-BuNC to give the monosubstituted compounds and , respectively when L is bonded Fe(1) bearing carbene ligand C(1). When a second displaced from electron-transfer catalysis both complex in which are linked Fe(2), respectively; moreover present solution bis-isonitriles bis-phosphites. structure has been determined X-ray diffraction results discussed terms assumption that exchange occurs an intermediate C(1) becomes metal atoms consequently can rotate about Fe-Fe axis.
