- 論文の詳細を見る
It has been found that 2-chlorothiophene is converted into the dimer type products by Amberlyst 15 or 100% orthophosphoric acid, the reaction yielding 4- and 5-(5-chloro-2-thienyl)tetrahydro-2-thiophenones and 4-(2-thienyl)-2(5<I>H</I>)-thiophenone together with 5-chloro-2,2′-bithienyl. The distribution of the products is considerably affected by the acid used and in the presence of phenol or anisole the reaction affords additionally 4-[5-(<I>p</I>-hydroxyphenyl)-2-thienyl] tetrahydro-2-thiophenone or 4-[5-(<I>p</I>-methoxyphenyl)-2-thienyl] tetrahydro-2-thiophenone, respectively.
