From metastable ion studies, Fourier transform ion cyclotron resonance experiments and semi‐empirical calculations, the unimolecular reaction of the (H 3 CO) 3 C + cation 1 is discussed. The first step of the reaction is an irreversible, 1,3‐CH 3 +transfer giving the H 3 COC(O)O(CH 3 ) 2 +ion, 2. This ion either cleaves or isomerizes into the ion‐neutral complex [H 3 COCO + , CH 3 OCH 3 ], 3. Since the H 3 COCO + cation is a very good CH 3 +donor, a CH + 3transfgr then occurs within the complex, 3, to yield the predominant fragment (CH 3 ) 3 O + .
