Cascade Reactions of Monoallenes

4 CASCADE REACTIONS INVOLVING ALLENES 6.4.1 Cascade Reactions of Monoallenes 

Allenes represent an important class of compounds used in transition metal-catalyzed reactions, especially palladium-catalyzed cascade reactions [101], in which they are used predominantly for the formation of 7t-allylpalladium species and carbopalladations.
