Versuchsvorschrift
Following the same general procedure as in Example I, 50 mmols of 2,6-dimethylphenol were reacted with 55 mmols of paraformaldehyde, 12.5 mmols of aqueous dimethylamine, and 100 mmols of 1,3-butadiene in 54 g of isopropyl alcohol at about 190° C. for 9-10 hours. The process resulted in the formation of 2,4-dimethylspiro[5.5]undeca-1,4,8-trien-3-one.
