摘要:

Palladium/Nobornene (Pd/NBE) cooperative catalysis, namely Catellani reaction, has recently emerged as a powerful approach for vicinal bis-functionalization of arenes. Using simple aryl halides as substrates, a number of nucleophiles and electrophiles have been coupled at the ipso and ortho positions respectively through selective reactions with the aryl-NBE-palladacycle (ANP) intermediate.
