CH3 11-dieny1)-phenol (11). A comparison of the infrared spectrum of this synthetic material with that of the material obtained by isomerization and methylation of the thermal rearrangement product proved their identity. Thus, the structure assigned by Claisen and Tietze to this rearrangement product is confirmed.-4 second proof of structure was accomplished by means of oxidative degradation with ozone. Ozonolysis of the methyl ...
