摘要：Ni compounds and PPh3 were usually used in stoichiometric amounts for the synthesis of bipyridine via coupling reaction. This reaction procedure was improved by using only catalytical amounts of nickel and PPh3 in the presence of zinc. This modification was mainly based on the changes of reaction addition order which could sufficiently utilize the Ni(O) generated in situ. Bipyridine can be synthesized by this catalytical procedure with satisfactory yield. The activity of three kinds of Ni complexes was compared in the reaction, and NiCl2 . 6H(2)O represented the highest activity.
