The review discusses the synthesis, structures and properties of transition metal and main-
group containing heterocyclopentadienes, with particular focus on …

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 …

Biphenylene is an antiaromatic compound that has a strained butadiene skeleton that joins
two benzene rings. Various methods for synthesizing the biphenylene core have been …

Computational methods have been used to better understand both the CpRuCl-and CpCo-
catalyzed and mediated cyclotrimerization of alkynes and the [2+ 2+ 2] cycloaddition of …

Substituted phenanthrenes and picenes were easily prepared by reaction of biphenylene or
angular [3] phenylene with various alkynes in the presence of a catalytic amount of [IrCl …

Activating the strong C–C σ-bond is a central problem in organic synthesis. Directly
generating activated C centers by metalation of structures containing strained four …

Catalytic C–C bond cleavage processes followed by further transformations are some of the
most fascinating reactions in chemistry and valuable organic synthesis tools. Herein, we …

A chelation-assisted oxidative addition of gold (I) into the C–C bond of biphenylene is
reported here. The presence of a coordinating group (pyridine, phosphine) in the …

This review discusses from a qualitative viewpoint three-dimensional structures
(hydrocarbons and carbon allotropes) that can be obtained from the 4, 6, 12-archimedean …
