Abstract
AbstractC–H activation of functionally rich molecules without the need for directing groups promises shorter organic syntheses and late-stage diversification of molecules for drug discovery. We highlight recent examples of palladium-catalyzed nondirected functionalization of C–H bonds in arenes as limiting substrates with a focus on the development of the concept of spatial anion control for direct C–H arylation.1 C–H Activation and the CMD Mechanism2 Nondirected C–H Functionalizations of Arenes as Limiting Substrates3 Nondirected C–H Arylation4 Spatial Anion Control for Direct C–H Arylation5 Coordination Chemistry with Spatial Anion Control6 Conclusion

Abstract
From the chiral Schiff base tridentate ligand LPh, unusual acetonitrile-bridged dinuclear palladium complex 1 and organopalladium complex 1' were synthesized selectively by using acetonitrile and ethanol, respectively. The chiral tridentate Schiff base ligand was bound to the palladium metal center with different chelation modes ([ONO] for 1 and [CNO] for 1'). Complex 1 constitutes the first example of dinuclear metal complexes connected only by a bridging acetonitrile, in which an exceptionally short C≡N bond distance [0.945(12) Å] of bridged acetonitrile was observed. To study the influence of a phenyl group attached to an imine, the phenyl-free ligand LH was prepared and used. In that case, an acetonitrile bridge was not observed. Theoretical calculation studies supporting the formation of 1 and 1' are favored.

Abstract
Oxidation of the palladium-phenyl N,N,Nmipp-pincer with Selectfluor leads to C–C coupling to give biphenyl; neither C–C nor C–F coupling is observed using the more sterically bulky N,N,Ndipp-pincer analogue.
