Thiepane Explained

Thiepane is the organosulfur compound with the formula (CH₂)₆S. Thiepanes are seven-membered ring heterocycles that contains sulfide.^[1] The parent thiepane has seldom been studied.

A variety of derivatives are known. Hexathiathiepane (CAS RN 17233-71-5, m.p. 90 °C) is CH₂S₆.^[2] A naturally occurring derivative is lenthionine, 1,4-(CH₂)₂S₅.

Thiepane itself may be a product of spontaneous coal fires in post-mining waste heaps.^{[3] [4]}
