Green Chemistry with Selenium Reagents: Development of Efficient Catalytic Reactions

摘要

Applications of selenium reagents in organic chemistry have developed rapidly over the past years, and comprehensive reviews on this area have appeared. Rather new, however, is the use of selenium-based catalysts in organic synthesis. We highlight new developments in organoselenium catalysis and in particular the use of selenium electrophiles and organoselenium compounds in carbonylation reactions and the oxidation of alkenes and carbonyl compounds. The use of organoselenium ligands for metal-catalyzed processes is not covered here; the topic has been reviewed recently else-where. Also their potential as efficient mimetics for selenoenzymes will not be discussed. In this Highlight we will focus on the catalytic use of selenium electrophiles for selenenylations and halogenations as well as the use of perseleninic acids as catalytic oxidants for various substrates.
