“…A further variant on the radical carbonylation/acyl radical cyclization theme involves the silyl carbonylation of hexa-1,5-dienes (Scheme 100). 248 Here, the sequence is initiated by addition of a tris(trimethylsilyl)silyl radical to the least substituted terminus of the diene. Carbonylation and acyl radical cyclization then ensues in the normal way.…”

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.
