1,5-Dithiacyclooctane (DTCO) is an organosulfur compound with the formula (CH₂CH₂)CH₂S)₂. This cyclic dithioether is a colorless oil that is soluble in polar solvents. It forms a variety of transition metal thioether complexes.

DTO can be oxidized to the bicyclic dication.[1]

Structure of (DTCO)PdCl₂.

DTCO was first prepared in 4% yield by dialkylation of 1,3-propanedithiol with 1,3-dibromopropane.[2]
