Phenol–keto tautomerism in tricyclic [10]annulenes; preparation and properties of 7b-methyl-2a,7b-dihydrocyclopent[cd]inden-2-(2H)-one

Abstract

The 2-‘phenol’ in the tricyclic [10]annulene series appears to exist entirely in the keto form (4); the ‘phenolate’ anion is readily formed, and can be methylated on oxygen, or on carbon to give isomer (9) exclusively.
