Thermolyses of Hexakis(trimethylsilyl)benzene and Pentakis(trimethylsilyl)toluene. The First Unique Trimethylsilyl-Triggered Rupture of Benzene Rings

Thermolysis of highly distorted hexakis(trimethylsilyl)benzene and pentakis(trimethylsilyl)toluene resulted in the formation of products arising from the ruptures of the aromatic rings.

5,6-Bis(trimethylsilyl)benzo[c]furan: A versatile building block for linear polycyclic aromatic compounds

Benzo[c]furans are a class of interesting compounds. Being very reactive, they readily undergo Diels-Alder cycloaddition with dienophiles to restore their aromaticity. For this reason, they can be utilized to construct six-membered ring compounds which are common building blocks of many natural and non-natural molecules. In connection with our use of silylated furans in the preparation of polysubstituted furans, we sought to extend our work to include silylated benzo[c]furans as well. Herein, we report the synthesis of the title molecule and its further manipulation for the preparation of several silylated linear polynuclear aromatic compounds. (C) 2000 Elsevier Science Ltd.

5,6-Bis(trimethylsilyl)benzo[c]furan: An isolable versatile building block for linear polycyclic aromatic compounds

Benzo[c]furans are a class of interesting and highly reactive compounds that readily undergo Diels-Alder cycloaddition with dienophiles to restore their aromaticity. Initially, the s-tetrazine approach established by Warrener was chosen for the synthesis of the title molecule. However, it was discovered that the rate of production of isobenzofuran from this approach was too slow to react with the fugitive arynes. Consequently, an alternative route was employed to realize the title molecule in a neat state. In this way, the reactions between the title molecule and arynes were successfully achieved. Herein, two synthetic approaches towards the title molecule and its further manipulation for the preparation of silylated linear polycyclic aromatic hydrocarbons (PAH) were reported.
