A practical meta C-H chlorination protocol is established via a Ru(0)-catalyzed ortho-metalation strategy. The use of N-chloro-2,10-camphorsultam as a new chlorinating agent is crucial for the success of the current reaction and an N-heterocyclic carbene (NHC) ligand could significantly enhance the reactivity of the catalytic transformation. The mechanistic studies reveal that an unusual ortho C-H ruthenation relay process with ortho chlorination of the C-Ru bond is probably involved.

Arylhydrazines react with potassium superoxide to give a variety of products, most of which are derived from interaction of aryl radicals with the solvent.Phenylhydrazine in toluene gives three isomeric metylbiphenyls, diphenylmethane and bibenzyl.In pyridine, the products identified were 2-, 3-, and 4-phenylpyridine.A more complex range of products was obtained from substituted phenylhydrazines.Products are consistent with a process in which superoxide ion abstracts hydrogen atoms from the hydrazines giving radical intermediates, including aryl radicals, which react with the solvents.
