Abstract
![]()
While ruthenium arene complexes have been widely investigated
for
their medicinal potential, studies on homologous compounds containing
a tridentate tris(1-pyrazolyl)methane ligand are almost absent in
the literature. Ruthenium(II) complex 1 was obtained
by a modified reported procedure; then, the reactions with a series
of organic molecules (L) in boiling alcohol afforded novel complexes 2–9 in 77–99% yields. Products 2–9 were fully structurally characterized. They are
appreciably soluble in water, where they undergo partial chloride/water
exchange. The antiproliferative activity was determined using a panel
of human cancer cell lines and a noncancerous one, evidencing promising
potency of 1, 7, and 8 and
significant selectivity toward cancer cells. The tested compounds
effectively accumulate in cancer cells, and mitochondria represent
a significant target of biological action. Most notably, data provide
convincing evidence that the mechanism of biological action is mediated
by the inhibiting of mitochondrial calcium intake.

Abstract
A family of complexes of the formula trans-[RuCl2(L)(R-pybox)] (R-pybox = (S,S)-iPr-pybox, (R,R)-Ph-pybox, L = monodentate phosphonite, PPh(OR)2, and phosphinite, L = PPh2(OR), ligands) were screened in the catalytic asymmetric transfer hydrogenation of acetophenone, observing a strong influence of the nature of both the R-pybox substituents and the L ligand in the process. The best results were obtained with complex trans-[RuCl2{PPh2(OEt)}{(R,R)-Ph-pybox}] (2c), which provided high conversion and enantioselectivity (up to 96% enantiomeric excess, e.e.) for the reduction of a variety of aromatic ketones, affording the (S)-benzylalcohols.

Abstract
The ruthenium-catalyzed allylation of aldehydes with allylic pro-nucleophiles has been demonstrated to be an efficient means to form carbon-carbon bonds under mild conditions. The evolution of this reaction from the initial serendipitous discovery to its general synthetic scope is detailed, highlighting the roles of water, CO, and amine in the generation of a more complete catalytic cycle. The use of unsymmetrical allylic pro-nucleophiles was shown to give preferential product formation through the modulation of reaction conditions. Both (E)-cinnamyl acetate and vinyl oxirane were efficiently used to form the anti-branched products (up to >20:1 anti/syn) and E-linear products (up to >20:1 E/Z) in high selectivity with aromatic, α,β-unsaturated, and aliphatic aldehydes, respectively. Attempts to render the reaction enantioselective are highlighted and include enantioenrichment of up to 75:25 for benzaldehyde.
