(4,4'-dimethylbipyridyl)NiMe2 was found to react thermally with 2-iodo-2',4',6'-trimethylbiphenyl (6) to produce a C-I insertion that is extremely distorted from square planarity, with the C-Ni-I plane intersecting the N-Ni-N plane by 33.4degrees. It was also found that [(dippe)RhCl](2) reacts with 6 to produce an eta(3)-benzylic complex by way of a rhodium migration to the methylated ring of the biphenyl unit.
