An evaluation of the intramolecular Diels-Alder reactions of Fischer carbene complexes was madefor complexes which have an all-carbon tether between the diene and dienophile. Specifically, both the cis- and trans-isomerq of the deca-2,7,9-trienyl car

The quaternary carbon in a 4H-carbazol-4-one can be introduced with high stereoprecision in the cyclohexadienone annulation of a 2-indolyl chromium carbene complex bearing an imidazolidinone chiral auxiliary. The chiral complex 12 was found to exist

Active polymerization catalysts, novel resin-bound diimine complexes of nickel(II) and palladium(II) are obtained by combinatorial synthesis and combined in a catalyst library. By tagging with fluorescent markers, the catalysts can be coded. Therefor
