The palladium catalyzed alkoxycarbonylation and aminocarbonylation of vinyl tosylates are described. A variety of ketone and aldehyde derived vinyl tosylates may be carbonylated in the presence of primary, secondary, and tertiary alcohols, or primary and secondary amines, to provide the corresponding esters and amides in good yields. The alkoxycarbonylation was applied to a short synthesis of isoguvacine

A new indolylphosphine ligand L1 has been developed for the palladium-catalyzeddirect C−H olefination of polyfluoroarenes with moisture and thermal stable alkenyl tosylates. The catalyst system employing L1 was found to be effective in this reaction with good structural and functional compatibility.
