ChemInform Abstract Starting with the sodium salts of the carboxylic acids (II) and epichlorohydrin (I), the thioglycidyl esters (IV) are prepared via sulfuration of the glycidyl esters (III).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
