 Title    Die Pd-katalysierte oxidative Kupplungsreaktion von Methylbenzoesäuremethylester The Pd-Catalyzed Oxidative Coupling Reaction of Methyl Methylbenzoates  
 Abstract    The Pd-catalyzed oxidative coupling reaction of methyl o-toluate gives, in the presence of a Pd/l,10-phenanthroline(phen)/Cu catalyst, exclusively, the para-linked biphenyldicarboxy-lates 1, 2, and 3. On the other hand, the meta-linked biphenyldicarboxylates 4 and 5, were predominantly formed in a catalyst system of Pd/2,4-pentanedione(acacH)/Cu, and under similar conditions 6 and 7 were also obtained from the coupling reaction of methyl m-toluate and methyl p-toluate, respectively. A reaction scheme has been proposed.
