Palladium-catalyzed Reaction of Diaryliodonium Salts with Allylic Alcoholst

Abstract

Palladium-catalyzed arylation of allyl and 2-methylallyl alcohols with diaryliodonium salts has been investigated. The reaction proved to be useful in converting aromatic hy d r ocarbons to the corresponding arylpropanals in two steps. Thus, 3-(p-isopropylpheny1) - 2 methylpropanal(cyclamaeldne hyde)a nd 3-(p-isobutylphenyl)-2-methylpropanaall(dlielyhyde), which are perfume for soap and toilet, were obtained from isopropylbenzene and isobutylbenzene in 78 and 82% yields, respectively.
