Abstract
The use of methanesulfonic acid as solvent and catalyst in the cyclocondensation of 1,2-dialkoxybenzenes with 3-methylbut-2-enoyl chloride to afford indanones 3, thus allowing the preparation of indenes 4 with improved overall yields, is reported. Additionally, structure of dimeric compound 7 a, formed in high yield by thermal treatment of 4a has been determined by com bination of spectroscopic means and selective deuterations.
