Ru2(CO)4(OOCR)2L2 sawhorse-type complexes containing axial 5-(4-pyridyl)-10,15,20-triphenylporphyrin ligands

Photo-activated CO-releasing molecules (PhotoCORMs) of robust sawhorse scaffolds [μ(2)-OOCR(1), η(1)-NH2CHR(2)(C = O] OCH3, Ru(I)2CO4]

A class of sawhorse-type ruthenium(i) complexes featuring a stable CORM sphere with diverse carboxylic and amino acid derivatives were synthesized and validated as lead structures for photo-activated CO-releasing molecules (PhotoCORMs). The CO release of these CORMs was triggered by 365 nm UV irradiation. Cell viability studies indicated that 3a and 3f were non-toxic both in the dark and in UV light, making them excellent lead structures for therapeutic CORMs.

An unexpected semi-hydrogenation of a ligand in the complexation of 2,7-bispyridinyl-1,8-naphthyridine with Ru3(CO)12

A novel formate-bridged diruthenium complex [(bpnp-H₃)Ru₂(μ-HCOO)(CO)₄] was prepared, in which the ligand bpnp was partially hydrogenated during the complexation of the ligand with Ru₃(CO)₁₂ in the presence of water.
