Two 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.

Abstract
Two 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
