Reaction of N,N-dimethyl-N-[(trimethylsilyl)methyl](polymethoxy-substituted benzyl)ammonium iodides 1a-e with cesium fluoride gave polymethoxy-substituted 5-[(dimethylamino)methyl]-6-methylene-1,3-cyclohexadienes 3 and 5 ([2,3] sigmatropic rearrangement products). However, these were quickly hydrolyzed to polymethoxytoluenes 8 during the aqueous workup. The pathway of the hydrolysis of 3 and 5 is discussed.
