New 4-Substituted 5-(1H-Pyrrol-2-ylmethyl)-4H-thieno[3,2-b]pyrroles and Their Reactions with N-Bromosuccinimide

Resumo

5-(1H-Pyrrol-2-ylmethyl)-4H-thieno[3,2-b]pyrroles were synthesized by condensation of N-substituted (4H-thieno[3,2-b]pyrrol-5-yl)methanols with pyrrole in the presence of Amberlyst 15 as catalyst. Treatment of the products with N-bromosuccinimide led to the formation of dark blue polymers insoluble in organic solvents.
