Carbon-Carbon Bond Cleavage Reaction Using Metallocenes,e attractive since many cases show the intermediates or the C–C bond cleavage steps in the reactions. Organic compounds are classified into three groups by the bond order of the C–C bond: (1) C–C single bond, (2) C–C double bond, and (3) C–C triple bond.

Book 2005d to be very characteristic and they have become very important, not only in the area of organic synthesis, but also in polymerization in industry. Metal complexes with one cyclopentadienyl ligand have also become popular as half sandwich complexes. The number of researchers in the field of metalloc

Construction of Carbocycles via Zirconacycles and Titanacycles,opment of synthetically useful methodologies for construction of carbocyclic compounds from different components. This review surveys applications of zirconacycles and titanacycles on construction of useful carbocyclic compounds from multi-components. A brief introduction into preparative methods for zirconacycles and titanacycles is also given.

Metallocene-Catalyzed Selective Reactions,ons, functional group interconversions, isomerizations, and C–C bond cleavage reactions. These reactions usually proceed with high degree of regio-, stereo- and enantioselectivity under mild reaction conditions. Moreover, they often display broad tolerance to the presence of other functional groups in the substrates.

Stereospecific Olefin Polymerization Catalyzed by Metallocene Complexes, environment of catalysts derived from a ligand structure (catalytic-site control) or a chiral center in the polymer chain (chain-end control). The mechanism of formation of isotactic and syndiotactic polymers in each monomer and catalyst is explained. Non-metallocene catalysts for stereospecific polymerization are also mentioned.
