In chemistry, aselone (also known as aselenoketone) is the structural analog of aketone whereselenium replacesoxygen. Their primary application is forchemical analysis.
Selenium-77 is one of theisotopes of selenium that isstable and naturally occurring, so selenoketone-containing chemicals can be analyzed bynuclear magnetic resonance spectroscopy (NMR). Selones can be used aschiral derivatizing agents for77Se-NMR.[1] Chiral oxazolidineselones can be used forstereoselective control ofaldol reactions, analogous to theEvans aldol reaction that usesoxazolidinones, which allows77Se-NMR to be used to determine thediastereomeric ratio of the aldol product.[2]
Selenobenzophenone reversibly dimerizes. It is known to undergocycloaddition with 1,3-dienes in reactions similar to theDiels-Alder reactions.[3]
