Blaulicht: Eine Palladium‐katalysierte Cyclotrimerisierung von 1,2‐Diarylacetylenen wurde entwickelt und in der Synthese von hoch substituierten 8,8a‐Dihydrocyclopenta[a]indenen eingesetzt. Ein solches Cycloaddukt, 1, zeigt eine ungewöhnliche aggregationsinduzierte Emission mit intensiver blauer Fluoreszenz (siehe Bild). Die Strukturen der Produkte wurden durch Kristallstrukturanalysen bestätigt.
Lewis acid, Me3SiOTf, has been shown to be a promising promoter for aza‐Michael reaction of relatively acidic primary amide with α,β‐unsaturated ketone. A sries of α,β‐unsaturated ketones was transformed to their corresponding β‐amido ketones with moderate yields under this reaction condition.
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.
