    Description / Table of Contents: Polyspiranes, 4. Syntheses and Coupling Reactions of Vinylcyclopropanes and Vinylidenedicyclopropanes Halogenated in Allylic PositionsSyntheses and coupling reactions of the vinylcyclopropanes and vinylidenedicyclopropanes respectively, brominated in allylic positions, 4-7, are described. Upon treatment with magnesium in ether, 4 yields the dimers 16-18, 5 the dimer 20, and 7 the cyclodimer 9. Upon treatment with phenyllithium, 6 and 7 undergo cyclization to yield 25 and 8, respectively.
    Notes: Es werden Synthesen und Kupplungsreaktionen der allylständig bromierten Vinylcyclopropane bzw. Vinylidendicyclopropane 4-7 beschrieben. Bei Behandlung mit Magnesium in Ether liefert 4 die Dimeren 16-18, 5 das Dimere 20 sowie 7 das Cyclodimere 9. Unter Einwirkung von Phenyllithium cyclisieren 6 und 7 zu 25 bzw. 8.
