A nitrogen-directed regioselective homocoupling reaction of aromatic compounds has been found to be catalyzed by a ruthenium complex in the presence of methallyl acetate as a hydrogen scavenger.

A palladium-catalyzed pyrazole-directed regioselective oxidative C(sp2)-H functionalization of the N-phenyl ring in N-phenylpyrazoles to afford either a biaryl bis-pyrazole (via dehydrogenative homocoupling) or N-(o-hydroxyphenyl)pyrazole (via C-H oxygena
Ruthenium-catalyzed C-H bond functionalizations of 1,2,3-Triazol-4-yl- substituted arenes: Dehydrogenative couplings versus direct arylations

experimental part, p. 2245 - 2253 (2010/09/04)
The chemoselectivity of ruthenium-catalyzed C-H bond arylations on triazol-4-yl-substituted arenes was found to depend on the substitution pattern of both substrates. While various aryl chlorides led to products stemming from direct arylations, ortho-substituted aryl halides in combination with ortho-alkylated arenes preferentially resulted in oxidative homo-couplings.
