    Description / Table of Contents: Reactions of Fulvenes with 1,3-Dipolar Compounds, III.  -  Reactions of Tetraarylfulvenes with 3-Methyl-2,4-diphenyl-1,3-oxazolium-5-olate2,3,4,5-Tetraarylfulvenes 1 react with 3-methyl-2,4-diphenyl-1,3-oxazolium-5-olate (2) at the semicyclic double bond to give 3, 4, and 5. The reduction of 4a yields 6 which with N-phenyltriazolindione gives 7. The pyrrolines 4 are photo labile; on irradiation the compounds 11 are formed. The structures of 7 and 11b have been clarified by X-ray crystallography.
    Notes: 2,3,4,5-Tetraarylfulvene 1 reagieren mit 3-Methyl-2,4-diphenyl-1,3-oxazolium-5-olat (2) an der semicyclischen Doppelbindung unter Bildung von 3, 4 und 5. Die Reduktion von 4a führt zu 6, welches mit N-Phenyltriazolindion das Addukt 7 liefert. Die Pyrroline 4 sind photolabil; bei Bestrahlung erhält man die Verbindungen 11. Die Konstitutionsformeln von 7 und 11b wurden durch Röntgenstrukturanalyse geklärt.
