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 carboxylicacid followed by decarboxylation at 180°C in quinoline in the presence of copper(I) oxide afforded

inhibitory concentration required to inhibit the growth of E. coli, M. luteus and A. niger. The series displays a wide range of activities with 2-chloro-3,5-dinitrothiophene (3a) or 2-bromo-3,5-dinitrothiophene (3c) showing the highest activity against all three organisms, while the simplest compound of the series, 2-nitrothiophene (3s) shows the smallest activity in each case. The mode of action of 3a and
