Polycyclic Aromatic Hydrocarbons

Polycyclic Aromatic Hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs) such as triphenylene, hexa-peri-hexabenzocoronene is of important for studies in several areas of research, from environmental chemistry to supramolecular chemistry or materials science. The PAHs targets of synthetic organic chemists, once simple compounds such as naphthalenes or phenanthrenes, are now more challenging objectives including strained molecules such as helicenes or fullerene fragments, nanostructures with interesting optical or electrical properties, and extended graphite-like compounds.

Template-Mediated for the Synthesis of Polycyclic Aromatic Hydrocarbons

Hexabenzocoronene (PAH1), directly by a thermally induced cyclodehydrogenation route starting from a precursor molecule adsorbed on a Cu (111) surface. This synthetic route is based on the following concept: first a precursor (hexaether) of the target PAH1 compound is synthesized and deposited in monolayers on a Cu surface. On heating this adsorbate layer, the precursor is completely dealkylated and converted by cyclodehydrogenation into the planar product.

Many aryl chlorides have been synthesized by using this methodology, including its extension to a “two-directional” double benzannulation sequence. For instance, 4, 10-dichlorochrysene, a nonlinear phenacene with a novel substitution pattern, is now readily available from bis (phenol).

Palladium-catalyzed annulation has been used as a means of forming polycyclic aromatic hydrocarbons. This methodology provides an exceptionally efficient route to a wide variety of substituted polycyclic aromatic hydrocarbons from readily available starting materials, affording the products in moderate to excellent yields.
