Hydrogenative Metathesis of Enynes via Piano-Stool Ruthenium Carbene Complexes Formed by Alkyne gem-Hydrogenation [PDF]

Journal of the American Chemical Society, 2020
The only recently discovered gem-hydrogenation of internal alkynes is a fundamentally new transformation, in which both H atoms of dihydrogen are transferred to the same C atom of a triple bond while the other position transforms into a discrete metal ...

Experimental and DFT studies of sulfadiazine ‘piano-stool’ Ru(ii) and Rh(iii) complexes

RSC Advances, 2020
While sulfadiazine (HLSZ) is extensively used to elaborate complexes of intriguing biological applications (e.g. topical antibiotic silvadene; silver sulfadiazine), the molecular structure modification of sulfadiazine or even other sulfa drugs by ...

Anticancer RuII and RhIII Piano-Stool Complexes that are Histone Deacetylase Inhibitors.

ChemPlusChem, 2016
The first examples of RuII and RhIII piano-stool complex histone deacetylase (HDAC) inhibitors are presented. The novel complexes have antiproliferative activity against H460 non-small-cell lung carcinoma cells that is comparable to the clinically used ...

Benchmarking the Fluxional Processes of Organometallic Piano-Stool Complexes [PDF]

Molecules, 2021
The correlation consistent Composite Approach for transition metals (ccCA-TM) and density functional theory (DFT) computations have been applied to investigate the fluxional mechanisms of cyclooctatetraene tricarbonyl chromium ((COT)Cr(CO)3) and 1,3,5,7-tetramethylcyclooctatetraene tricarbonyl chromium, molybdenum, and tungsten ((TMCOT)M(CO)3 (M = Cr ...

Cationic Niobium‐Sandwich and Piano‐Stool Complexes [PDF]

Chemistry – A European Journal, 2020
AbstractThe syntheses of the homoleptic bis(arene) niobium cations [Nb(arene)2]+ (arene = C6H3Me3, C6H5Me) with 16 valence electrons and heteroleptic arene‐carbonyl cations [(CO)Nb(arene)2]+ (arene = C6H3Me3, C6H5Me) and [(arene)M(CO)4]+ (arene = C6H3Me3, C6H6) obeying 18 valence electrons are described. Stabilization of these complexes was achieved by

Synthesis, structural characterization and cytotoxic activity of two new organoruthenium(II) complexes [PDF]

Journal of the Serbian Chemical Society, 2008
Two new p-cymene ruthenium(II) complexes containing as additional ligands N-methylpiperazine ([(η6-p-cymene)RuCl2(CH3NH(CH2)4NH)]PF6, complex 1) or vitamin K3-thiosemicarbazone ([(η6-p-cymene)RuCl2(K3tsc)], complex 2) were synthesized starting from [(η6 ...

Piano-stool ruthenium(II) complexes with maleimide and phosphine or phosphite ligands: synthesis and activity against normal and cancer cells.

Dalton Transactions, 2023
In these studies, we designed and investigated cyto- and genotoxic potential of five ruthenium cyclopentadienyl complexes bearing different phosphine and phosphite ligands.
