CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishTwo general classes of reactions leading to heterocycles are reviewed: the sequential hydroarylation(hydrovinylation)/cyclization of alkynes containing proximate nucleophilic and electrophilic centers, a process which combines the palladium-catalyzed cis addition of an aryl or vinyl unit and a hydrogen atom to the carbon–carbon triple bond with the formation of a new bond between the nucleophile and the electrophile; the palladium-catalyzed cyclization of alkynes containing proximate nucleophiles with organopalladium complexes, which is based on a trans heteropalladation/reductive elimination tandem reaction.
