The direct activation of C-O bonds in allylic alcohols in water as a suspension medium by palladium complexes has been accelerated by carrying out the reactions in the presence of a carboxylic acid. The palladium-catalyzed allylation of anilines using allylic alcohols directly gave allylic anilines in good yields. (c) 2006 Elsevier Ltd. All rights reserved.

Benzofuran, naphthofuran, and indole frameworks were expediently constructed at ambient temperature from arene bromides with ortho O- and N-substituents containing double or triple bonds via radical cyclization process promoted by Sml2.

The intramolecular Heck reaction of aromatic amines and ethers using palladium/imidazoliumsalts is described. The use of tetra-n-butylammonium halide salts facilitates the reactivity of aromatic chlorides. An unexpected and novel palladium-mediated cyclisation is also described leading to the formation of a tricyclic adduct.
