Alkylation with geminal dihalides gives 1,3-dithiepanes. Oxidation gives the cyclic disulfide 1,2-dithiane:[3]
It forms self-assembled monolayers on gold.[4]
It is also used in polyadditions along with 1,4-butanediol to form sulfur-containing polyester and polyurethanes containing diisocyanate.[5][6][7] Several of these polymers are considered biodegradable and many of their components are sourced from non-petroleum oils.[8]
