Barluenga, Jose,Florentino, Lucia,Aznar, Fernando,Valdes, Carlos

scheme or table, p. 510 - 513 (2011/03/22)

Aryl nonaflates are employed as electrophiles in the Pd-catalyzed cross-coupling with tosylhydrazones affording di-, tri-, and tetrasubstituted olefins. Fine tunning of the reaction conditions are required to accomplish the coupling successfully, includin
