Anodic oxidation of 1,2-bis-(trimethylsilyl)-1,2-diphenylethane in methanol affords a 65:35 mixture of 1,2-dimethoxy-1,2-diphenylethane (dl:meso = 10:1 and diphenylacetaldehyde dimethylacetal. The results can be interpreted in terms of a 1,2-diaryl-2-methoxyethyl cation, which can undergo either nucleophilic attack by solvent or rearrangement to a 2,2-diaryl-1-methoxyethyl cation. Experiments testing the generality of the reaction are described.
