palladiumヽatalyzed alkynylationSummary In this chapter the authors discuss the Pd-catalyzed reactions of aryl, alkenyl, benzyl, alkyl, and acyl electrophiles with metal nucleophiles leading to carbon-metal bond formation. The Sonogashira and related Heck-type alkyne hydrogen substitution reactions are ...
