(pi-allyl)Tricarbonyliron lactone complexes in organic synthesis: a useful and conceptually unusual route to lactones and lactams

Article Abstract:

(pi-allyl)tricarbonyliron lactone and lactam complexes provide new approaches for the construction of organic compounds including lactones, lactams and masked dienylic alcohols. They are readily available from a variety of starting materials, stable in the solid state, soluble in a variety of solvents and exhibit high stereoselectivities. This review focuses on the chemistry of these complexes. The discussion includes the reactions of the complexes with various systems such as acids and bases and phosphines.

Synthesis, structure, and reactivity of organometallic pi-complexes of the rare earths in the oxidation state Ln3+ with aromatic ligands

Article Abstract:

Rare earth organometallic compounds have been widely synthesized and are used as stoichometric organic synthesis reagents. The molecular structure and most successful preparation methods for group 3 elements, scandium, yttrium and lutetium, and 4F-elements, lanthanum to ytterbium, in the oxidation state Ln3+ are presented. All currently known rare earth organometallic compounds and spectroscopic data related to them are presented in the tabular form.

Intramolecular coordination in organometallic compounds of groups 2, 12, and 13

Article Abstract:

The structural, physical and chemical characteristics of the organometallic compounds of groups 2, 12 and 13 are discussed. The organometallic compounds are intramolecularly coordinated. These are prepared by transmetalation, reactions from halogen precursor compounds, or by metalation. The intramolecular coordination is identified by X-ray crystal structure analysis, gas-phase electron diffraction, and spectroscopies.
