Homologous series (C{sub 15}-C{sub 24}) of novel 3-n-alkyl-1,2-dithianes and 3-n-alkyl-6-methyl-1,2-dithianes have been identified in immature sediments. The identification of these compounds was based on comparison of mass spectra and chromatographic data with those of synthesized 3-methyl-6-tridecyl-1,2-dithiane. In addition, 4-methyl-3-(3,7,11-trimethyldodecyl)-1,2-dithiane, 4-(4-8,12-trimethyltridecyl)-1,2-dithiane, 5-methyl-4-(3,7,11-trimethyldodecyl)-1,2,3-trithiepane, and a 1,2-dithiane possessing a pentakishomohopane carbon skeleton were tentatively assigned on the basis of mass spectral characteristics, selective chemolysis, and desulfurization. The occurrence of these cyclic di- and trisulfides with linear, acyclic isoprenoid and hopanoid carbon skeletons in thermally immature sediments indicates that inorganic polysulfides are incorporated into functionalized lipids during the early stages of diagenesis.
