Nach 3 stdg. Kochen unter RiickfluB wurde das Pyridin i.Vak. abgedampft und der Ruckstand aus Benzol-F'yridin (1 : 1) umkristallisiert.

“…The two aldehydes 6 and 7 most likely result from oxidative carbon=carbon double bond cleavage. As for compounds 4 and 5, the thermal dimerization of aryl butadiene 1 has been observed earlier [25][26][27]. Beyond these compounds, we observed many unidentified broad signals by NMR analysis (see FigureS16), suggesting the polymerization of 1.…”
