title: Catalytic alkenylation of phenylpyridines with terminal alkynes by a [12]metallacrown-6 ruthenium(II) compound.
abstract: Two new [12]metallacrown-6 compounds, [M(II)(6)(SMe)(12)] [M = Ru (1), Zn (2)], were constructed from a dimethyl sulfoxide decomposed methylthiol product to doubly bridged metal centers. The Ru(II) compound can prompt alkenylation reactions of phenylpyridines with alkynes to generate monoalkenylated arylpyridines in moderate yields with high regioselectivity and stereoselectivity.
