| Reactant | 1,3-Butadiene | HCID 7845 | — |
| Reactant | Phenol, 4-[(dimethylamino)methyl]-2,6-dimethyl- | HCID 39355 | — |
| Solvent | Toluene | HCID 1140 | — |
| Product | 2,4-Dimethylspiro[5.5]undeca-1,4,8-trien-3-one | HCID 13531455 | 78% |
Reaction Steps
Following the same general procedure as in Example I, 5 mmols of N,N-dimethyl-4-aminomethyl-2,6-dimethylphenol were reacted with 20 mmols of 1,3-butadiene in 40 g of toluene at 189°-205° C. for six hours. GC analysis showed a 78% yield of 2,4-dimethylspiro[5.5]undeca-1,4,8-trien-3-one.
