Abstract

Abstract Alkoxytropylium-Ionen zeigen bei der Reaktion mit Malodinitril/Triäthylamin ambidentes Verhalten. Mit 1 Moläquivalent Methoxytropyliumtetrafluoroborat (2b-BF 4) entsteht unterhalb 0 ein Gemisch von [2-, 3-und 4-Methoxy-cycloheptatrien-(2.4. 6)-yl]- malodinitril (1Ab+ 1Bb+ 1Cb). Dieses Isomerengemisch setzt sich in siedendem 1.2-Dichlor- äthan in Gegenwart von Triäthylammoniumchlorid zum 8.8-Dicyan-heptafulven (3) um; in ...
