Several complexes containing Ru(dppe)Cp* fragments attached to heterocyclic ligands were obtained from polycyanocarbons. Reactions of Ru{CCC(CN)C(CN)2}(dppe)Cp* with LiCCSiMe3 and LiOCHCH2 gave binuclear {[Ru(dppe)Cp*]CC-c-CC(CCSiMe 3)N(Ha?OH2)CCC(CN)}2(NN) 2 and Ru{c-CCHC[C(CN)2]CHCHO}(dppe)Cp* 4 [together with known Ru{CCCMeC(CN)2}(dppe)Cp* 3], respectively, while lithiation of Ru(CCCCH)(dppe)Cp* and subsequent reaction with TCNE afforded Ru{CC-c-CC(CN)C(O)NH[C(CN)2]}(dppe)Cp* 6 and Ru{CC-c-CCHC[C(CN)2]NHCMeN}(dppe)Cp* 7, as well as known {Ru(dppe)Cp*}2{μ-CCC[C(CN)2]C[C(CN) 2]CC} 5. A second product from the earlier described reaction between TCNE and Ru(CCCCI)(dppe)Cp* was identified as Ru{CC-c-CC(CN)C(CN) C(NH2)C(CN)2}(dppe)Cp* 9. X-ray determined structures of 2, 4, 6, 7 and 9 are reported together with plausible routes by which they may be formed.

The complex Ru{C≡CC(CN)=C(CN)2}(dppe)Cp* (1), containing the new tricyanovinylethynyl (3,4,4-tricyanobut-3-en-1-ynyl) ligand, undergoes ready substitution of the 3-cyano group by nucleophiles (Nu) such as H, Me, Pri, Bu, But, mesityl, OMe, OBut, OCH2CH=CH2, NHEt, NEt2, and PPh2 to give Ru{C≡CC(Nu)=C(CN)2}(dppe)Cp. The X-ray diffraction structures of several of the resulting complexes are reported and, for the mesityl and PPh2 products, show that isomerization to the 3,5-dimethylbenzyl and oxidation to the phosphine oxide have respectively occurred.
