Abstract
A new method for the preparation of naphtho[1,2-b]- and naphtho [2,1-b]thiophene structures by arylation of acrylic acid with α- and β-iodonaphthalene and subsequent oxidation of the resulting trans-naphthylacrylic acids with thionyl chloride in the presence of triethylbenzylammonium chloride is proposed.
