The silicon–sulfur compound bis‐1,3‐[di(2,6‐diisopropylphenoxy)]disiloxane‐1,3‐dithiol was obtained from silicon disulfide and 2,6‐diisopropylphenol in a reaction catalyzed by imidazole or 4‐(dimethylamino)pyridine (DMAP). The disiloxane‐1,3‐dithiol is produced in a low yield but in a repeatable manner and can be isolated as colorless crystals. The X‐ray crystal structure of the compound reveals a linear or close‐to‐linear Si–O–Si angle and a mutual trans position of the two hydrosulfido groups. The compound forms a chelating mononuclear complex with cadmium ions. In the complex, the sulfido groups adopt a cis conformation, and the Si–O–Siangle deviates from linearity. The molecular structure of the compound is discussed on the basis of DFT calculations.
