Palladacycles as Precatalysts for Heck and Sonogashira Cross-Coupling Reactions

摘要: Abstract Alkenes and terminal alkynes are commonly available building blocks for a variety organic syntheses. The state-of-art transition metal-catalyzed Mizoroki-Heck Sonogashira cross-couplings represent versatile reliable protocols further modification these molecules. In the past few decades, reactions were found generally to proceed-well in presence of homogenous palladium catalyst. Recent advancements showed that palladacycles become one most promising catalyst systems transformations. It should be attractive note palladacyclic complexes usually thermally stable easily synthesized. This book chapter summarizes recent developments on cross-couplings. Some unique catalytic performances relevant transformations also described.
