, p. 3485 - 3488 (2002)
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, provid

Two novel hydrocarbon cations with a tropylium ion ring fused by two spiro[4,5]deca-2,4-dienes, 9 and 10, were synthesized by a six-step sequence starting from 1,6- and 1,5-diacetyl-1,3,5-cycloheptatrienes, respectively. The pKR+ val
