A process for the preparation of the compound of the formula ##STR1## wherein R.sup.1 is OH, which comprises the steps of a) treating the compound of the formula ##STR2## with an inorganic fluoride, of the formula M.sup.2 F wherein M.sup.2 is an alkali metal cation, at an elevated temperature in the presence of a compound of the formula R.sup.4 P.sup.+ Z.sup.- and a compound of the formula R.sup.5 vic (COW).sub.2 wherein R.sup.4 and R.sup.5 are each selected from optionally substituted (C.sub.6 -C.sub.10)aryl and optionally substituted (C.sub.1 -C.sub.6)alkyl, and W is halo; to form the compound of the formula; ##STR3## and b) i) treating the compound of the formula IV with an aqueous solution of a base, of the formula MOH, wherein M is an alkali metal cation, and ii) treating the product of step i) with a mineral acid. A compound of the formula ##STR4## wherein R.sup.1 is selected from the group consisting of, halo, R.sup.7 O, R.sup.7 COO and N(R.sup.8).sub.2 wherein R.sup.7 is (C.sub.1 -C.sub.6)alkyl or (C.sub.6 -C.sub.10)aryl and each R.sup.8 is selected from hydrogen and R.sup.7 with the proviso that R.sup.7 is not methyl when R.sup.1 is R.sup.7 O.
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
