Abstract:RECENT ADVANCES IN THE ELECTROPHILIC ADDITION OF CHALCOGEN ATOMS TO ALKENES. Organochalcogen compounds (containing S, Se and Te) are interesting from biological point of view, but also in their use as intermediates in obtaining complex molecules or even for exploring their properties. In this way, chalcogen electrophiles are very powerful reactants and can be added to alkenes to form a three-membered intermediate called chalcogeniranium ion. This specie reacts with different nucleophiles to undergo a series of… Show more
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.
