Organoruthenium chemistry in chemistry is the study of organometallic compounds containing a carbon to ruthenium chemical bond ^[1]. The interest is mostly academic although several organoruthenium catalysts are of commercial interest. The chemistry has many similarities with organoiron chemistry with iron one element up in group 8 of the periodic table. The most important reagents for the introduction of ruthenium are ruthenium(III) chloride and triruthenium dodecacarbonyl. The related compound Ru(CO)₅ is less attractive for this purpose because it decomposes:

Ru₃(CO)₁₂ + 3 CO 3 Ru(CO)₅

Compared to organopalladium chemistry ruthenium has fewer applications partially due to the higher coordination number and the wider variety in oxidation state (-2 to +6).

[edit] Ligands

The most important ligands for ruthenium are:

• carbon monoxide as in metal carbonyls
• phosphines. BINAP is an asymmetric ligand for many ruthenium compounds in asymmetric synthesis ^{[2] [3] [4] [5]}.
• cyclopentadienyl ligands. The parent compound ruthenocene is unreactive compared to mononuclear complexes such as chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium.
• various arenes and dienes for example cumene in (cymene)ruthenium dichloride dimer ^[6] or acenaphthylene ^[7] The compound Ru(COD)(COT) is capable of dimerizing norbornadiene:

• metal carbenes, notably Grubbs' catalyst, an import catalyst in olefin metathesis.
• halides. chlorine ligands are easily replaced by alkyl, aryl or hydride ligands
• hydrogen. Transition metal hydrides are important in C-H bond activation.
