Convenient catalytic synthetic methods for the preparation of unsym. disulfanes RSSR1 (R = dodecyl, cyclohexyl, benzyl, furan-2-yl, etc.; R1 = Me, cyclohexyl, benzyl, pyridin-2-yl, etc.) are described. Na-exchanged X type zeolite (Na-X), com. available as MS-13X, effectively catalyzes thiol-disulfane exchange reactions with 1.0 equiv of thiols RSH and 2.5-3.0 equiv of disulfanes R1SSR1 at 10°C to room temperature under air. The reactions of sterically-hindered disulfanes or electron-deficient thiol substrates require high temperatures under inert atmospheres to maintain the good product yields. Various functionalized thiols and disulfanes are tolerant in the present catalytic systems, affording the corresponding unsym. disulfanes in good-to-high yields (up to 96%). The Na-X catalyst was successfully recycled 10 times without loss of yield. Preliminary mechanistic studies suggest the involvement of base-catalyzed SN2-S displacement and/or addition-elimination mechanisms, assisted by hydrogen-bonding interactions. The results came from multiple reactions, including the reaction of 1,2-Diphenyldisulfane(cas: 882-33-7COA of Formula: C12H10S2)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. COA of Formula: C12H10S2 The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.
