The Diels‐Alder adducts of functionalized dienes with P‐chloro‐bis(trimethylsilyl)methylenephosphine can be aromatized, except in a few particular cases, thus opening a general route to functionalized phosphinines. The aromatization procedure differs with the substituents. Intermediates such as secondary cyclic phosphines could be characterized and even isolated. In some cases, aromatization and 1,5 sigmatropic shift of a trimethylsilyl group were observed and hydrogenolysis of the CSi bond as well.
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.
