Palladium and nickel catalysed cross-coupling reactions of organozincs

Palladium and nickel catalysed cross-coupling reactions of organozincs 

In comparison with the Ni catalysed cross-coupling14 as well as the Cu promoted or Cu catalysed cross-coupling,15 the Pd catalysed cross-coupling16 has exhibited a broader scope with respect to the two carbon groups to be coupled,

Various Pd or Ni catalysed procedures for aryl-aryl coupling have been developed,10-1214 16 but those involving organozincs19 appear to be among the
