Abstract
By heating a dilute solution of the potassium salt of 5-(p-hydroxyphenyl)-1-bromopentane (I) it is possible to obtain spiro-[5:5]-undeca-1,4-diene-3-one (II) in good yield. During this intramolecular alkylation a phenolic ring is changed into a cyclohexadienone. The term desaromatisation is applied to this reaction.
