Notizen:
1,1-Di-2-thienylethanol (1) undergoes light-induced (Δ 〉 400 nm) dehydration to afford 1,1-di-2-thienylethylene (2). Compound 2 is selectively converted into 1,6-cyclodimers under thermal or photochemical conditions. In these latter case the non-aromatic Diels-Alder adduct 3 can be characterized. An ET mechanism involving a methyldithienylcarbenium ion (9) as electron acceptor and a chain mechanism is proposed to account for the products.
