Usage

General Description

(S)-1-Phenylethanethiol, also known as alpha-phenylethyl mercaptan, is a chemical compound with the formula C8H10S. It is a colorless liquid that is highly volatile and has a strong, unpleasant odor. (S)-1-Phenylethanethiol is commonly used as a flavoring agent in the food and beverage industry due to its onion-like aroma. It is also used in the production of perfumes and as a reagent in organic synthesis. However, it is important to handle (S)-1-Phenylethanethiol with caution, as it is highly toxic if ingested and can cause irritation to the skin, eyes, and respiratory system.

Accelerated reduction and solubilization of elemental sulfur by 1,2-aminothiols

Nucleophilic 1,2-aminothiol compounds readily reduce typically-insoluble elemental sulfur to polysulfides in both water and nonpolar organic solvents. The resulting anionic polysulfide species are stabilized through hydrogen-bonding interactions with the proximal amine moieties. These interactions can facilitate sulfur transfer to alkenes.

Phosphorus pentasulfide mediated conversion of organic thiocyanates to thiols

In this paper we report an efficient and mild procedure for the conversion of organic thiocyanates to thiols in the presence of phosphorus pentasulfide (P2S5) in refluxing toluene. The method avoids the use of expensive and hazardous transition metals and harsh reducing agents, as required by reported methods, and provides an attractive alternative to the existing methods for the conversion of organic thiocyanates to thiols.

Dutch Resolution: Separation of enantiomers with families of resolving agents. A status report

Dutch Resolution is the term given to the use of mixtures (families) of resolving agents in classical resolutions. In this status report an overview is given of the latest results and new (possible) families of resolving agents are introduced. The concept of families is discussed as well as the factors that come into play on use of families. Practical aspects of Dutch Resolution in particular and resolutions in general are discussed.
