ABSTRACT:
Arenes, such as benzoic acid and substituted benzoic acids, are readily thallated by thallium(III) compounds such as the trifluoroacetate and subsequently reacted with palladium chloride and simple olefins, dienes, allylic halides, vinyl halides, vinyl esters, or unsaturated cyclopropanes or unsaturated cyclobutanes to give isocoumarins.
