New bonding modes, fluxional behavior, and reactivity in dinuclear complexes bridged by four-electron donor unsaturated hydrocarbons
Article Abstract:
New bonding modes, fluxional behavior, and reactivity in dinuclear transition metal complexes bridged by four-electron donor unsaturated hydrocarbons are discussed. The type of coordination in dinuclear systems varies while moving from one system to the other. The similarity in the dynamic behavior of these complexes are due to the migration of the bridging hydrocarbyl ligand from one atom to the other, rotation about the C-C bond, and the internal rearrangement of the dinuclear cluster. The synthesis and reactions involving the dinuclear propargyl radicals attached to fulvalne ligands are given.

Transition metal-boryl compounds: synthesis, reactivity, and structure
Article Abstract:
The synthesis, structure, spectroscopic characteristics and chemical reactions related to metal-boryl compounds were reviewed. The transition metal-boryl compound possesses a covalent two-center, two-electron bond occurring between the metal center and a three-coordinate, sp2-hybridized boron atom. The synthesis of the compound involved the reaction of anionic transition metal complexes with haloboranes and in the absence of these complexes, reactions required a combination of oxidative addition and reduction of hydrogen.

The nature of the bonding in transition-metal compounds
Article Abstract:
Progress in the understanding of the binding interactions in transition metal compounds is considered. It has been possible to develop several partitioning schemes and apply them after they were initially calculated with reliable quantum chemical techniques.
