Progress on palladium-catalyzed and iridium-catalyzed substitution reactions of aryl and allylic electrophiles will be reported. The palladium-catalyzed reactions form products of aromatic substitution with amine, carbonyl enolate and related nucleophiles. Iridium-catalyzed reactions form products of allylic substitution with similar nucleohpiles with control of regioselectivity and enantioselectivity. This lecture will present selections of recent results from one or more of these two types of metal-catalyzed substitution reactions with particular emphasis on the mechanisms of these reactions and how this information has pointed to classes of catalysts that display improved activity, longevity or selectivity.
