Usage

General Description

S-Ethyl thiopropionate is an organic compound with the chemical formula C5H10OS. It is a colorless liquid with a strong odor, commonly used in the food and beverage industry for its fruity and sweet aroma, resembling that of pineapple. It is also utilized in the production of fragrances and as a flavoring agent. S-Ethyl thiopropionate is classified as a potentially hazardous substance, as it can cause irritation to the skin, eyes, and respiratory system upon contact or inhalation. Therefore, proper safety precautions should be observed when handling this chemical.

Investigations of the Thermal Responsiveness of 1,4,2-Oxathiazoles

The first systematic study of the thermal rearrangement/fragmentation of 5,5-disubstituted 1,4,2-oxathiazoles into isothiocyanates is reported. Structure-activity relationships reveal that the choice of substituent at the 5-position of the 1,4,2-oxathiazoles is the predominant factor to influence the ease of fragmentation.

Zinc promoted convenient and general synthesis of thiol esters

Synthesis of thiol esters from acyl chlorides and thiols in the presence of activated zinc is described. The recovery of zinc and its reuse makes the procedure more economic.

ACTIVITY OF 1-OXA-3-THIACYCLOALKANES AND 2-ALKYLTHIOOXACYCLANES IN FREE-RADICAL ISOMERIZATION

It was established that radical isomerization to alkyl esters of thiocarboxylic acids, initiated by tert-butyl peroxide at 130-150 deg C, is a common reaction for five-, six- and seven-membered 1-oxa-3-thiacycloalkanes and 2-alkylthiooxacycloalkanes.Under analogous conditions 2-diethylaminotetrahydropyran isomerizes to N,N-diethylvaleramide.The relation between the structure and the reactivity of 1-oxa-3-thiacycloalkanes and 2-alkylthiooxacycloalkanes in free-radical isomerisation was studied by the method of competing reactions.Depending on the ring size, the activity of the 1-oxa-3-thiacycloalkanes increases in the order : 1,3-oxathianes 1,3-oxathiolanes 1,3-oxathiepanes.
