概要	An improved synthesis of tetrakis(2-thienyl)methanes, where an aromatic nucleophilic substitution is the key reaction for the introduction of the fourth 2-thienyl group, has been developed, thus, reaction of tris(2-thienyl)methyl anion with 2-fluoro-5-cyanothiophene smoothly proceeded to give (5-cyano-2-thienyl)-tris(2-thienyl)methane in good yield. Alkaline hydrolysis of the cyano group to carboxylic acid followed by decarboxylation at 1808C in quinoline in the presence of copper(I) oxide afforded the parent tetrakis(2-thienyl)methane in 50% total yield from the trithienylmethane.
