Resumo(s)
ln order to obtain precursors for a ring C convergent method to thienodibenzothiophene by an
intramolecular Heck reaction, 3-bromo-2-((Z)-2-bromovinyl)thiophene 1 was prepared from 3-bromothiophene
by ortho-directed lithiation followed by electrophilic formylation and formation of the bromovinyl moiet via
the dibromo compound.
