Abstract

The vinylidene complex [Ru(eta(5)-C5H5)(PPh3)(2)(=C=CHUr)][X] (X = PF6, OTf, Ur = uracil) is a versatile precursor for a range of organometallic complexes containing pendant uracil groups. Using appropriate conditions the vinylidene complex may be selectively transformed into alkynyl Ru(-C= CUr)(eta(5)-C5H5)(PPh3)(2), carbene [Ru(eta(5)-C5H5)(PPh3)(2)(=C{OMe}-CH(2)Ur)][X] and alkenyl-phosphonio species [Ru(E-CH=C{PPh3}Ur)(eta(5)-C5H5)(PPh3)(2)][X]. The synthesis of the related alkenyl-phosphonio complexes [Ru(E-CH=C{PPh3}R)(eta(5)-C5H5)(PPh3)(2)][X] (R = Ph, C6H4-3-OMe) is described; these undergo a further orthometallation reaction: the mechanism of this latter reaction appears to proceed via dissociation of a ruthenium-bound PPh3 ligand.
