Intramolecular C(sp²)−H Bond Activation in 6,6′-Dimethoxy-2,2′-Bipyridine with Gold(III). Crystal and Molecular Structure of the First N′,C(3) “Rollover” Cycloaurated Derivative

Treatment of 6,6′-dimethoxy-2,2′-bipyridine (bipy2OMe) with gold(III) acetate results in the exclusive formation of a cyclometalated gold(III) derivative arising from activation of the C(3)−H bond of a pyridine ring.
