New organometallic chemistry of ruthenium and osmium

Animesh Chakravorty

Abstract: The reaction of Schiff monobases of 2,6-diformyl-4-methylphenol with ruthenium(II) and osmium(II) has afforded a new family of orthometalated organometallics. Synthesis, characterization and reactivity are briefly discussed in this article.

Decarbonylation of Salicylaldehyde Activated byp‐Cymene Ruthenium(II) Dimer: Implication for Catalytic Alkyne Hydrothiolation

et al. 2016

A stoichiometric C–H activation/decarbonylation of salicylaldehyde by [(η6‐p‐cymene)RuCl2]2 gave a carbonyl derivative [(η6‐p‐cymene)RuCl(CO)(Ph‐O)] (1) without the use of CO gas. A variety of polar phosphines were then incorporated into compound 1 to give new RuII cationic catalysts, [(η6‐p‐cymene)Ru(CO)(Ph‐O)L]BF4 (2–8). These were used to catalyse the hydrothiolation of alkynes with a range of thiols in aqueous THF to give anti‐Markovnikov E‐linear vinyl sulfides in high yields.

Cyclometalated Osmium Compounds and beyond: Synthesis, Properties, Applications

The synthesis of cyclometalated osmium complexes is usually more complicated than of other transition metals such as Ni, Pd, Pt, Rh, where cyclometalation reactions readily occur via direct activation of C–H bonds. It differs also from their ruthenium analogs. Cyclometalation for osmium usually occurs under more severe conditions, in polar solvents, using specific precursors, stronger acids, or bases. Such requirements expand reaction mechanisms to electrophilic activation, transmetalation, and oxidative addition, often involving C–H bond activations. Osmacycles exhibit specific applications in homogeneous catalysis, photophysics, bioelectrocatalysis and are studied as anticancer agents. This review describes major synthetic pathways to osmacycles and related compounds and discusses their practical applications.
