1,3,5-trithiane
Also known as 1,3,5-Trithian, s-trithiane, 1,3,5-trithiacyclohexane, trimethylene trisulfide, sym-trithiane, trithioformaldehyde, thioform, sym-Trithian
1,3,5-Trithiane is the chemical compound with the formula (CHS). This heterocycle is the cyclic trimer of the otherwise unstable species thioformaldehyde. It consists of a six-membered ring with alternating methylene bridges and thioether groups. It is prepared by treatment of formaldehyde with hydrogen sulfide.

Trithiane is a building block molecule in organic synthesis, being a masked source of formaldehyde. In one application, it is deprotonated with organolithium reagents to give the lithium derivative, which can be alkylated. (CHS) + RLi → (CHS)(CHLiS) + RH (CHS)(CHLiS) + RBr → (CHS)(CHRS) + LiBr (CHS)(CHRS) + HO → RCHO + .... Trithiane is the dithioacetal of formaldehyde. Other dithioacetals undergo similar reactions to the above.
