    Description / Table of Contents: Vinyl Cations, 31. Synthesis and Solvolysis of (Bromocyclopropylmethylene)cyclopropane(Bromocyclopropylmethylene)cyclopropane (3f) has been synthesized by bromination of (cyclo-propylmethylene)cyclopropane (14) and subsequent dehydrobromination. The solvolysis of 3f was investigated in solvents of various ionizing power. The reaction products and the solvolysis rates including salt effects show that the solvolysis proceeds via a vinyl cation mechanism involving intimate- and solvent separated ion pairs and dissociated ions.
    Notes: (Bromcyclopropylmethylen)cyclopropan (3f) wurde durch Bromierung von (Cyclopropyl-methylen)cyclopropan (14) und anschließende Dehydrobromierung dargestellt. Die Solvolyse von 3fwurde in Lösungsmitteln verschiedener Ionisierungsstärke untersucht. Die Reaktionsprodukte sowie die Solvolysegeschwindigkeit unter Einbeziehung von Salzeffekten zeigen, daβ die Solvolyse über einen Vinylkationenmechanismus unter Beteiligung von inneren und äußeren Ionenpaaren sowie von freien Ionen abläuft.
