Organic transformations catalyzed by cyclopentadienyl complexes of Group 9 metals (cobalt,
rhodium and iridium) are the key steps of the total synthesis of various natural products …

The recent developments in cobalt catalysis are compiled in this review covering the years
2000 through 2007. Special focus is directed towards cobalt-catalysed ring-formation …

The cyclotrimerization of acetylenic compounds is a useful method for the construction of
three new bonds in a one-step process. Although symmetry-allowed, there is a paucity of …

Organocobalt compounds in organic synthesis have three characteristic reactions. The first
occurs because cobalt has a high affinity to carbon–carbon π‐bonds or carbon–nitrogen π …

Treatment of phenols or anilines containing a sulfonyl group in the presence of a
hypervalent iodine reagent promotes a formal dearomatizing [2+ 3] cycloaddition reaction on …

A new approach to nonracemic [7] helicene-like molecules has been developed.
