Usage

General Description

Diisoamyl disulfide is a chemical compound that is commonly used as a flavor additive in food products such as cheese, meat and fruit flavors. It is also found in essential oils extracted from garlic and onions, giving them their characteristic smell. Diisoamyl disulfide is known for its strong, pungent odor and is often used in small amounts to impart a savory, meaty flavor to food products. In addition to its use in food, it is also used as a fragrance ingredient in perfumes and as a component in industrial and household cleaning products. However, high concentrations of diisoamyl disulfide can be irritating to the eyes, skin and respiratory system, and it is recommended to handle it with precaution and in well-ventilated areas.

One-pot conversion of alkyl halides to organic disulfides (disulfanes) using thiourea and hexamethyldisilazane (HMDS) in DMSO

A practical method to synthesize symmetric disulfides from alkyl halides has been developed. Using this procedure primary, secondary, benzylic and allylic disulfides were prepared by treating the corresponding alkyl halides with thiourea and HMDS in DMSO at 50 °C within 10-24 h in high yields.

Graphene Oxide-Assisted One-Pot and Odorless Synthesis of Symmetrical Disulfides Using Primary and Secondary Alkyl Halides (Tosylates) and Thiourea as Sulfur Source Reagent

Graphene oxide is described as a heterogeneous oxidant for the synthesis of symmetrical disulfides through the in situ generation of thiols from primary and secondary alkyl halides (tosylates) and thiourea in wet acetonitrile. A variety of alkyl halides and alkyl tosylates can be converted to corresponding disulfides in good to excellent yields. This strategy is free of foul-smelling thiols.

One-pot efficient synthesis of disulfides from alkyl halides and alkyl tosylates using thiourea and elemental sulfur without contamination by higher polysulfides

An efficient and odorless synthesis of disulfides from alkyl halides using thiourea and elemental sulfur in the presence of sodium carbonate in wet polyethylene glycol (PEG 200) at 40 C without contamination by higher polysulfides has been developed. This procedure was then extended to preparation of disulfides from alkyl tosylates at 70 C.
