Group 4 ansa-cyclopentadienyl-amido catalysts for olefin polymerization
Article Abstract:
Research was conducted to examine monocyclopentadienyl-amido catalysts for olefin polymerization. Their high productivity and ability to generate unique polymer architectures with increased processability triggers continued interest in academic as well as industrial laboratories. An improved understanding of the ethylene/styrene propagation mechanism may result in new catalyst structures that offer higher incorporation efficiencies, levels and molecular weights.

New insights into an old mechanism: /2 + 2~ photocycloaddition of enones to alkenes
Article Abstract:
The basic characteristics of photocycloaddition reactions of enones and mechanistic proposals are presented. Several of the proposals such as Corey-de Mayo Exciplex systems, Bauslaugh's biradical proposal, Bauslaugh-Schuster-Weedon biradical mechanism, identifying intermediate reactive enone, tracing of biradical intermediates and synthesis of adduct 1,4-biradicals are also discussed.
