Abstract
The reaction of aryl iodides or vinyl triflates with a variety of olefins in supercritical carbon dioxide (scCO(2)), in the presence of triethylamine and palladium on carbon, has been investigated. Methyl acrylate, styrene and acrylonitrile afford vinylic substitution products. Butenone reacts with aryl iodides to form a mixture of vinylic substitution and hydroarylation (formal conjugate addition) products, n-Butyl, vinyl ether gives rise to the formation of products arising from the alpha- and beta-arylation process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
