摘要: Abstract The reactions of bis-trimethylsilylacetylene and bis-trimethylsilylbutadiyne with various transition metal carbonyls have been studied. Both form stable complexes iron, cobalt manganese. infrared spectral data indicates that for the group IV substituted ligands pi-accepting ability increases in order C < Si Sn. Mass provides evidence existence novel bis-cyclobutadiene iron fragments also unknown tetra-silylcyclobutadiene.
