A general, practical palladium-catalyzed cyanation of (hetero)aryl chlorides and bromides.
Angew. Chem. Int. Ed. Engl. 52(38) , 10035-9, (2013) Playing it safe: The nontoxic cyanide source K4 [Fe(CN)6]·3H2O can be used for the cyanation of (hetero)aryl halides. The application of palladacycle catalysts prevents poisoning during catalyst formation, thereby allowing for low catalyst loadings, fast reac... |
