Conjugate addition vs. vinylic substitution in palladium-catalysed reaction of aryl halides with β-substituted-α,β-enones and -enals
Autor: Sandro Cacchi, W. Fedeli, Giorgio Ortar, A. Amorese, S. Cerrini, Antonio Arcadi, E. Bernocchi
Publikováno v: Tetrahedron. 45:813-828
The reaction of β-substituted-α,β-enones and -enals with aryl halides in the presence of a palladium catalyst has been investigated. The outcome of the reaction was found to be greatly dependent on the nature of the added base. Tertiary amines ten
