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.

One-pot synthesis of organic disulfides (disulfanes) from alkyl halides using sodium sulfide trihydrate and hexachloroethane or carbon tetrachloride in the poly(ethylene glycol) (PEG-200)

Abstract Symmetric disulfides are produced by treating their corresponding organic halides including benzylic, allylic, primary and secondary halides with Na2S·3H2O and C2Cl6 or CCl4 in PEG-200 at room temperature in high yields.

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.
