Metal Complexes of π-Ligands Containing Organosilicon Groups

摘要: Publisher Summary This chapter discusses the metal complexes of π -ligands containing organosilicon groups. Organometallic compounds both groups and transition atoms have received much attention in several research laboratories. The organic ligands are classified, as is usual transition-metal chemistry, according to number electrons contributed by vacant orbitals. Some examples illustrate use protect reactive sites synthesis that cannot be obtained a direct reaction. Thus, chromium or cobalt carbonyl monosubstituted acetylenes directly, either because lack reaction polymerization and/or secondary reactions ligand. migration from ligand believed key step mechanism olefin hydrosilylation catalyzed nickel–phosphine complexes. structures silylated cyclobutadiene were established mass spectrometry X-ray diffraction studies. Various substituted silacyclopentadienes react with iron give stable η 4 -silacyclopentadiene Silacyclohexadienes may, principle, act 4-electron donors. Cyclopentadienyl tricarbonyl manganese can also metalated -butyllithium then converted into derivatives. Aromatic hexacarbonyl on prolonged heating corresponding 6 -arene
