Abstract
The conventional palladium catalysts used in Heck reactions-Pd(OAc)(2) + n P(aryl)(3)-suffer from extensive PC-bond cleavage at temperatures that would be necessary to activate aryl chlorides and electron-rich aryl bromides (> 120 degrees C). This type of catalysts is, thus,not s uitable to perform Heck reactions with non-activated substrates, espec ially with the technically interesting aryl chlorides.
