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 (bipy(2OMe)) 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.
