The Heck reaction as a sharpening stone of palladium catalysis

Article Abstract:

This comprehensive article covers the fundamentals of the vast field of the Heck-type reactions ubiquitously used in the synthesis of organic compounds. The Heck-type reactions are propelled by palladium-driven catalytic cycles, which lead to multi-step synthetic pathways involving a preactivation step, oxidative addition, migratory insertion, termination, and palladium hydride elimination.

Palladium-catalyzed reactions of allenes

Article Abstract:

The role of pi-allylpalladium intermediate in the organic synthesis is central to the palladium-catalyzed reactions of allenes with carbon and heteroatom nucleophiles. The application and reactivity of the pi-allylpalladium species in the synthesis of natural products using allenes and mechanistic aspects of reactions involved are discussed.
