Abstract

1. The yield of tert-butylthiophene reaches 73% if the alkylation of thiophene with isobutylene is run employing static conditions, under pressure, in the presence of H3PO4/kieselguhr catalyst. 2. The ratio of the 2-: 3-isomers decreases from 3.0∶1 down to 2.2∶1 when the temperature is raised from 75 up to 175°.
