Significance

The paper describes the synthesis of an α-diketone precursor of bis-2-thienyl-2,6-anthracene, which is known as a promising candidate for organic field-effect transistor (OFET) (J. Am. Chem. Soc. 2005, 127, 2406-2407). The synthesis starts with the Suzuki coupling to install thiophene moieties, followed by hydrolysis and Swern oxidation. The authors subsequently investigate the photochemical conversion of the precursor into the target acene in solution and as a film.
