Abstract
The title cation was synthesized from 1,6-diacetylcyclohepta-1,3,5-triene by a six-step sequence involving an aldol reaction, the Nazarov cyclization, the Shapiro reaction and hydride abstraction, and its pKR+ value was found to be 13.2, providing a new access to highly stable hydrocarbon cations.
