Abstract

A new synthesis has been described for coloured dihydrofurylium salts of the hemicyanine type based on the reaction of 2,2,5-trisubstituted 3-benzoyl-methylidene-2,3-dihydrofurans with organomagnesium or organolithium compounds, tertiary aromatic amines or 1,1-diarylethylenes.

Zusammenfassung

Es wurde eine neue Synthese für Dihydrofuryliumfarbsalze beschrieben. Die Synthese gründet sich auf die Reaktion von 2,2,5-trisubstituierten 3-Benzoylmethyliden-2,3-dihydrofuranen mit den Magnesium- bzw. Lithiumorganischen Verbindungen, tertiären aromatischen Aminen oder unsymmetrischen Diarylethylenen.
