20. 3 C-H dehydrogenated cross-coupling reaction has been reported. In the literature, the authors suggest that the coupling occurs via the Friedel-Crafts-type reaction mechanism, (a) Li, Z.; Li, C.-H. J. Am. Chem. Soc. 2005, 127, 6968. For related reactions, see:

25. Iv probably by air in the course of the reaction. The reaction under an inert atmosphere did not afford 4Ni. For an oxidant-promoted C-H bond activation reaction, see: Newman, C. P.; Casey-Green, K.; Clarkson, G. J.; Cave, G. W. V.; Errington, W.; Rourke, J. P. Dalton Trans. 2007, 3170.
26. The reaction of 1Ni with a platinum(IV) salt in toluene/AcOH provided a platinum(IV)-bridged cofacial diporphyrin. See ref 3b. However, none of such diporphyrins was detected in the reaction in toluene/ DMF.
