A Polycyclic Aromatic Hydrocarbon Bearing an All-cis Tetrabenzo[5.5.5.5]fenestrane (Fenestrindane) Core Merged with Two Hexa-peri-hexabenzocoronene Units

Dedicated to Prof. T.-Y. Luh of National Taiwan University on the occasion of his 70^th birthday

Abstract

The successful merging of two multiply tert-butylated hexa-peri-hexabenzocoronene (HBC) units with all-cis-tetrabenzo[5.5.5.5]-fenestrane (fenestrindane) at two opposite aromatic rings was described. Due to steric inhibition of the tert-butyl substituents near the merging region with the fenestrindane core, attempts to construct a highly warped but fully conjugated polycyclic aromatic hydrocarbon that contains two cycloheptatriene rings failed to materialize.

Key words

arenes - cross-coupling - cyclization - fused-ring systems - Diels–Alder reaction

• 17 Typical Experimental Procedure for the Synthesis of 3 Into a dried flask equipped with a magnetic stirrer was added a solution of compound 19 (30 mg, 16 μmol) in CH₂Cl₂ (100 mL). The solution was degassed by bubbling argon through it for 10 min, and then a solution of FeCl₃ (500 mg) in MeNO₂ (2.0 mL) was added dropwise via a syringe. After 20 min, the reaction was quenched by addition of MeOH (100 mL). The solvent was removed under reduced pressure, and the residue was purified by flash silica gel chromatography (eluent: 30% CH₂Cl₂ in hexanes) to give compound 3 (27 mg, 90%) as a light yellow solid; mp >250 °C. ¹H NMR (400 MHz, CDCl₃): δ = 9.93 (s, 2 H), 9.70 (s, 2 H), 9.56 (s, 2 H), 9.46 (s, 2 H), 9.41 (br, 12 H), 9.37 (s, 2 H), 8.30–8.28 (m, 2 H), 7.75–7.73 (m, 2 H), 7.26–7.22 (m, 2 H), 7.10 (s, 2 H), 6.76–6.73 (m, 2 H), 6.00 (s, 2 H), 1.98 (s, 18 H), 1.92 (s, 18 H), 1.91 (s, 18 H), 1.89 (s, 18 H), 1.63 (s, 18 H). ¹³C NMR (100 MHz, CDCl₃): δ = 149.2, 149.1, 148.1, 145.4, 144.9, 144.1, 139.0, 131.2, 131.2, 130.6, 130.5, 130.5, 130.4, 130.3, 130.1, 129.7, 128.4, 127.6, 127.4, 126.5, 125.3, 125.1, 124.7, 124.1, 124.0, 123.8, 123.6, 121.2, 120.8, 120.7, 120.6, 120.2, 119.5, 119.1, 119.1, 119.0, 118.7, 71.0, 66.5, 64.0, 35.9, 35.8, 32.2, 32.0, 31.9.
