Catalytic Dehydrogenation ofo-Alkylated oro-Alkoxylated Iodoarenes with Concomitant Hydrogenolysis

Palladium-catalyzed dehydrogenation of suitable chains bonded to an ortho position of an iodoarene has been achieved by two methods both involving oxidative addition of the iodoarene to palladium(0) and palladacycle formation under mild conditions.
