C-P coupling constants from the series (indicated in Table 2) and in this instance, it seems reasonable to conclude that from all DCB substrates, it is this complex that would depict the more electron poor character at the coordinated -CN moiety and thus probably, the faster hydration rate.

note
-
The alternative of nickel(0) going on and off for catalysis would imply that all nickel(0) intermediates required to yield the complete hydration of 1,3- and 1,4-DCB would have been formed within 72 h, at 180 °C. In the case of 1,2-DCB the same premise might imply additionally, that at the same temperature the free nickel catalysts should coordinate to the 1,2-phthalamide produced in situ in a fashion not conducive towards further hydration, therefore, not producing the corresponding dicarboxylic acid. Still, the selectivity and yield afforded at 120 °C for such product and not to 2-cyanobenzamide which would be expected to form otherwise, specially if free [(dippe)Ni] catalysts were to react randomly, an explanation based on an intramolecular migration of these species was found to be reasonable, at least for the time being.
