    摘要: We report the design of a catalytic, bifunctional template that binds heterocyclic substrate via reversible coordination instead of covalent linkage, allowing remote site-selective C—H olefination of heterocycles. The two metal centers coordinated to this template play different roles; anchoring substrates to the proximity of catalyst and cleaving the remote C—H bonds respectively. Using this strategy, we demonstrate remote site-selective C—H olefination of heterocyclic substrates which do not have functional group handles for covalently attaching templates. For instance the olefination can be an alkenylation of a 3-phenylpyridine with an acrylate alkyl ester selective for the meta position of the phenyl group with respect to the pyridine, or can be an alkenylation of a quinoline with an acrylate alkyl ester selective for the 5-position of the quinoline.
