1,n-dicarbanionic titanium intermediates from monocarbanionic organometallics and their application in organic synthesis
Article Abstract:
This paper examines the various steps involved in the organic synthesis involving monocarbanionic organometallic reagents. Research reveals that these compounds in the presence of titanium derivatives behave as dicarbanionics when reacting with electrophiles.

Three-membered-ring-based molecular architectures
Article Abstract:
The unique physical and chemical properties of the cyclo-propane moieties are demonstrated to understand the design of unusual and fascinating molecular assemblies of three-membered carbocycle rings. The cyclopropyl moieties could be attached to a pre-existing oligocyclic skeleton by substitution or by transformation of other functional substituents while alternatively multiple cyclization of an oligocyclopropyl-substituted subunit could lead to a more complex oligocycloproply-substituted framework.

Metal-initiated amination of alkenes and alkynes
Article Abstract:
The amination of olefins can be done through direct addition of nucleophiles to activate alkenes. The activation of alkenes is accomplished with late-transition-metal catalysts which allows the olefins to become susceptible to attack by amido species. The other alternative for amine activation route utilizes N-H oxidative addition to electron rich metal centers. If the oxidative addition would be coupled to an alkene/alkyne insertion process and reductive elimination, catalytic cycle for olefin can be achieved.
