摘要：

Thieno[3,4-b]thiophene has been obtained in greater than 50% yield starting from 3,4-dibromothiophene by a sequence of Pd II-Q I-catalysed cross-coupling with trimethylsilylacetylene, bromine-lithium exchange, thiolation with elemental sulfur and ring-closure in aqueous medium. © 1990, Taylor & Francis Group, LLC.
