• ; polycyclic aromatic hydrocarbon; Prato reaction; Introduction Investigations into the structures and properties of geodesic polyarenes began with the synthesis of corannulene (1, C20H10) in 1966 [1][2] and were greatly stimulated by the discovery of buckminsterfullerene (2, C60) in 1985 (Figure 1) [3

• ]. Whereas fullerenes comprising complete three-dimensional polyhedra can be classified as “closed” geodesic polyarenes, curved subunits of fullerenes are regarded as “open” geodesic polyarenes [4]. The fullerenes constitute one family of geodesic polyarenes, and bowl-shaped polycyclic aromatic hydrocarbons

• ′,2′-c]fluorene, also known as truxene (Figure 1), is a heptacyclic polyarene with C3 symmetry that can be envisaged as three fluorenes that are superimposed through a common central benzene ring [2][3]. Truxene has been used as a starting compound, or a core unit, for larger star-shaped polyarenes

The potential of this catalyst for the preparation of polyarenes is illustrated by a

• synthesis of two functionalized decacyclenes in a one-pot transformation in which three C–C bonds are formed with high efficiency. Keywords: alkynes; gold(I) catalysis; hydroarylation; polyarenes; Introduction Electrophilic activation of alkynes in functionalized substrates by gold catalysts allows for

• synthesis of large polyarenes [40][41][42][43], which are related to the fullerenes [44], we used the palladium-catalyzed arylation reaction as the main tool [45][46][47][48]. We decided to try the triple hydroarylation of substrates of type 1 to give 3,9,15-triaryldiacenaphtho[1,2-j:1',2'-l]fluoranthenes 2
