Selective transfer semihydrogenation of alkynes to yield alkenes was achieved with commercial first and second generation Hoveyda-Grubbs catalysts and formic acid as a hydrogen donor. This catalytic system is distinguished by its selectivity and compatibility with many functional groups (halogens, cyano, nitro, sulfide, alkenes). The metathetic activity of the ruthenium catalysts may be utilized in tandem sequences of olefin metathesis plus alkyne reduction.

The transmetallation reaction between [(eta6-arene)RuCl2]2 (eta6-arene = C6H6 (benzene) (1); 1-Me-iPr-C6H4 (cymene) (2); 1,2,4,5-Me4-C6H2 (durene) (3); 1,2,3,5-Me4-C6H2 (isodurene) (4)) and the aminoaryl-mercury derivatives Hg{Q-dmba}2 (Q-dmba = 1-{C6H3-3-F-6-CH2NMe2} (a); 1-{C6H3-3-Me-6-CH2NMe2} (b); 1-{C6H2-2,3-OCH2O-6-CH2NMe 2} (c); 1-{C6H2-2,4-(MeO)2-6-CH2NMe 2} (d); 1-{C6H4CH2NMe2} (e)) affords the corresponding C,N-cycloruthenated complexes [(eta6-arene)RuCl{Q-dmba}]. All complexes were characterised by 1H and 13C{1H} NMR. The reaction seems to be governed by steric rather than by electronic factors: an increase in the number of alkyl substituents in the eta6-arene ligand or the presence of bulky groups ortho to Hg in the starting material leads to a significant decrease of the yields of the desired cycloruthenated products.

New phenoxybenzylidene ruthenium chelates were synthesised from the second generation Grubbs catalysts bearing a triphenylphosphine ligand (or its para-substituted analogues) by metathesis exchange with substituted 2-vinylphenols. The complexes behave like a latent catalyst and are characterized by an improved catalytic behaviour as compared to that of the known analogues, i.e., they exhibit high catalytic inactivity in their dormant forms and a profound increase in activity after activation with HCl. The strong electronic influence of substituents in the chelating ligand on the catalytic activity was demonstrated. The catalytic properties were tested in ROMP of cyclooctadien (COD) and a single selected norbornene derivative.

Cyclic voltammograms in acetonitrile of 1a, 2a, and 3a display one-electron oxidations at 0.72, 0.71, 0.63 V, respectively, consistent with a Ru(III/II) couple. Compounds 1b, 2b, and 3b show a pH independent couple at pH<2 and a pH dependent couple consistent with a one-electron, one-proton process at pH values from ca. 2 to 11. Past pH 11 this redox process becomes pH independent again, and the compounds become unstable. The one-electron nature was verified by bulk electrolysis and spectroelectrochemical measurements.
