Reaction of 1-benzothiepine (4), whose synthesis has been improved, with trimethyloxonium tetrafluoroborate yields 1-methyl-1-benzothiepinium tetrafluoroborate (5). Compound 5 rearranges to methyl 1-naphthyl sulfide (6) on heating in acetonitrile. The reaction rate 5 → 6 was determined at one temperature (75°C).
