Notes:
The reaction of 3,5-di-tert-butyl-4-oxo-2,5-cyclohexadienylidene (3d) with pyridine affords 2,6-di-tert-butyl-4-(2,4,6-tri-tert-butylpyridinio)phenolate (1d) - which is not accessible by the classical route via pyrylium salts - in reasonable yield. Carbene 3d is generated by thermal decomposition of the corresponding quinone diazide 2d in cyclohexane. Betaine 1d shows the expected large solvatochromism.
