A ruthenium carbene catalyst containing a 1,2-dicarbadodecaborane(12)-1,2-dithiolate ligand was synthesized, and the structure was determined by single crystal X-ray diffraction. This new ruthenium carbene catalyst can catalyze the ring opening metathesis polymerization (ROMP) reaction of norbornene to give the corresponding Z-polymer (Z/E ratio, 98:2) in high yield (93%); ring opening cross metathesis (ROCM) reactions of norbornene/5-norbornene-2-exo, 3-exo-dimethanol with styrene or 4-fluorostyrene to give the corresponding Z-olefin products (Z/E ratios, 97:3-98:2), respectively, in high yields (73%-88%); cross metathesis (CM) reactions of terminal alkenes with (Z)-but-2-ene-1,4-diol to give high Z-olefin products in low yields; homometathesis reactions of terminal alkenes to give olefin products in low yields. Like other ruthenium carbene catalysts, the new complex tolerates many different functional groups. DFT calculations were also performed in order to understand the process of forming Z-olefin products and the decomposition process of catalysts.

The reaction of <(Ru(eta6-C6H6)Cl2)2> with the sodium salt of (S)-N-(1-phenylethyl)salicylideneamine (HL-L) in CH2Cl2 led to a diastereomer mixture of (RRu,SC)- and (SRu,SC)- 1a and 1b, in a ratio of 86:14.Mediated by AgPF6 in acetone at -30 to -35 deg C, the chloride ligand in 1a/1b was substituted by 4-methylpyridine (4Me-py), 2-methylpyridine (2Me-py) or triphenylphosphane (PPh3) to give the two diastereomers 2a/2b of PF6, the pure diastereomer 3 of PF6 and the two diastereomers 4a/4b of PF6.At room temperature in <(2)H6>acetone, under equilibrium conditions, the diastereomer ratio 2a:2b was 67:33, 3 was diastereomerically pure and the ratio 4a:4b was 93.4:6.6.Variable-temperature 1H NMR spectroscopy of complexes 2a/2b and 4a/4b from -80 deg C to room temperature demonstrated configurational lability of the ruthenium configuration.Since equilibration occured during reaction and work-up, the ruthenium configuration was not retained in the substitution reactions.Diastereomer 2a was obtained diastereomerically pure by crystallisation.The diastereomers 4a and 4b were separated and examined by variable-temperature NMR spectroscopy.The crystal structures of the (RRu,SC) diastereomer of complex 1 and of the thermodynamically more stable (RRu,SC) diastereomers 2a and 4a” were determined by X-ray analysis.A conformational analysis based on the NMR spectroscopic results showed that two main factors govern the orientation of the 1-phenylethyl group relative to the moiety (L’=Cl, 4Me-py, 2Me-py or PPh3): (i) the face-on orientation of the phenyl substituent with respect to the ?-bonded aromatic benzene ligand and (ii) the steric demand of the unidentate ligands with respect to the 1-phenylethyl group.

The applicability of ruthenium alkylidenes as initiators in the ring opening metathesis polymerization (ROMP) of cyano group containing liquid crystalline norbornene derivatives has been investigated. Complexes featuring N-heterocyclic carbenes as the co-ligands like RuCl2(H2IMes)(PCy3)(=CHPh) polymerized (±)-exo,endo-bicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic acid bis-[5-(4?-cyano-biphenyl-4-yloxy)pentyl] ester, while RuCl2(PCy3)2(=CHPh) failed. Especially RuCl2(H2IMes)(=CH-o-(Pr2i)O-C 6H4) proved to be an effective initiator, operating also in ambient conditions. The corresponding side chain liquid crystalline polymers were isolated in high yields and showed considerably narrow polydispersities. The thermal properties of the polymers were compared to the corresponding polymers prepared by a molybdenum based initiator system. Only subtle differences were found, proving at the first time the suitability of ruthenium initiators for the preparation of cyano group substituted side chain liquid crystalline polymers.

The structures of compounds 4, 5, 10 and 12 were determined by X-ray crystallography. Cyclic voltammetry of the halide-bridged complexes revealed shifts in the redox potentials of the metals, as compared to mononuclear model compounds. The shifts are consistent with electron donation between the metals through the halide bridge. Ru/Au complexes 8-11, which are bridged only by the bidentate phosphine, exhibited minimal electronic effects between the metal centers. This limited interaction between the metal centers in 8-11 is corroborated by UV/vis spectroscopy.
