Abstract
Dithia [3] metacyclo [3]--(2, 3)-,-(2, 4)-,-(2, 5)-, and-(3, 4) thiophenophanes were prepared by dithiol bis-alkylations and were oxidized with m-chloroperbenzoic acid to the corresponding tetraoxides. Pyrolysis of the tetraoxides under a reduced pressure gave the corresponding [2] metacyclo [2] thiophenophanes together with many unexpected compounds. The conformations of the obtained products are also discussed.
