• ABSTRACT The reaction of bis(trimethylsilyl) sulfide with different substituted thiiranes under tetrabutylammonium fluoride (TBAF) catalysis leads to the synthesis of 3,7‐disubstituted‐1,2,5‐trithiepanes, through regioselective reaction of a thiosilane intermediate with another molecule of episulfide, followed by intramolecular oxidation of two sulfur units. When using bis(trimethylsilyl)selenide, the reaction with thiiranes and TBAF affords a smooth access to a novel class of disubstituted‐1,2,5‐dithiaselenepanes.
