Acyl- and Thioacylketenes: Synthesis of 3-Benzoly-4-phenylthiet-2-one

Insights into the valence tautomerization 1 ⇌ 2 were obtained using dibenzylketene and benzoyl(thiobenzoyl)ketene as examples. The former dimerizes, whereas the latter cyclizes to the thietone, whereby an equilibrium exists in the gas phase. The ketenes were generated by flash pyrolysis from furan a...

Zusammenfassung:Insights into the valence tautomerization 1 ⇌ 2 were obtained using dibenzylketene and benzoyl(thiobenzoyl)ketene as examples. The former dimerizes, whereas the latter cyclizes to the thietone, whereby an equilibrium exists in the gas phase. The ketenes were generated by flash pyrolysis from furan and thiophenedione, respectively.
