Heterocycles constitute one of the most interesting divisions of organic chemistry. A majority
of the compounds produced by nature as well as significant numbers of compounds …

Abstract [2+ 2+ 2] Cycloaddition reactions belong to the not even large class of reactions,
which can be catalyzed or mediated by a significant number of different transition metals …

Synthetic sequel: The transition‐metal‐catalyzed [2+ 2+ 2] cycloaddition is an established
method for the construction of carbocyclic frameworks but is often plagued by poor …

Cobalt cyclopentadienyl complexes incorporating a fumarate and a CO ligand (see picture)
efficiently catalyze inter‐and intramolecular [2+ 2+ 2] cycloadditions of alkynes, nitriles …

The transition-metal-catalyzed [2+ 2+ 2] cycloaddition of alkynes with nitriles is a useful and
atom-economical method for the synthesis of substituted pyridines. The use of isocyanates …

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 …

Synthetic procedures for bis (η6-arene) metal derivatives and aspects of their reactivity are
reviewed. Attention is focused on early transition metals (Groups 4–6) but, when necessary …

A highly practical, general method for catalytic formation of substituted pyridines from a
variety of unactivated nitriles and α, ω-diynes is given. The reactions which were catalyzed …

Recent advances on the synthesis of six-membered carbo-and heterocyclic compounds
including functionalized benzenes, 1, 3-cyclohexadienes, pyridines, pyridones, pyranones …

Two recently reported air-and water-stable di-Rh complexes based on 1, 3-bis (3′-
butylbenzimidazol-2′-ylidene) benzene were utilized as catalysts for hydrosilylation …
