The Applications of Palladacycles as Transition-Metal Catalysts in Organic Synthesis

Abstract

This account summarizes our recent work on palladacycles in organic synthesis and describes some unique catalytic properties of palladacycles as transition-metal catalysts for some useful transformations. Asymmetric induction has been realized by using chiral palladacycles as transition-metal catalysts. The influence of the C−Pd bond of palladacycles on their catalytic activity has been revealed. The reaction selectivity can be switched by appropriate choice of an sp 2 -or sp 3 -hybridized C,P-palladacycle catalyst.
