Abstract

MONTMORILLONITE: A MILD AND EFFICIENT RECYCLABLE HETEROGENEOUS CATALYST FOR DECARBOXYLATION OF 3, 4- DIALKOXYTHIOPHENE-2, 5-DICARBOXYLIC ACIDS OR ITS SALTS.

N. Madhava Rao*, M. Rajesh, M. Thirumala Chary, B. M. Choudary

ABSTRACT

Proton and metal ion-exchanged Montmorillonite catalyzes the decarboxylation of 3, 4-alkylene dioxythiophenedicaboxylic acid or its salts or 3, 4- dialkoxythiophenedicarboxylic acid or its salts respectively, in presence of less expensive and reusable heterogeneous catalyst. The main objective of the present invention is to provide an improved process for the preparation of 3, 4-alkylenedioxythiophenes or 3, 4-dialkoxythiophenes which is simple, high purity and industrially applicable. The main objective is to generate a process for 3, 4-alkylenedioxythiophenes or 3, 4 - dialkoxythiophenes which is ecofriendly, commercially viable and easily adoptable in plant scale.

Keywords: Montmorillonite, decarboxylation, 3, 4- alkylenedioxythiophenedicarboxylic acid or its salts, 3, 4-alkylenedioxythiophene.
