The order of pK(R)+ values of these cations was found to be 7 \u003e 8 \u003e 6. A comparison of the values between 1, 1-dialkyl- and 1, 1-spiroalkylated 1H-azulenium cations with the same number of carbon atoms at the I-position provided the results of 7 \u003e 1 and 8 \u003c 3. The cation 8 shows a relatively lower pKR+ value to those of 3 and 7 probably due to its slightly bulkier propyl groups from which solvation stabilization of 8 under the conditions suffers. An intermolecular charge-transfer interaction between the cations and dibenzo-24-crown-8 was also studied. (c) 2006 Elsevier Ltd.
