(Cymene)ruthenium dichloride dimer is the organometallic compound with the formula [(cymene)RuCl22. This red-coloured, diamagnetic solid is a reagent in organometallic chemistry and homogeneous catalysis. The complex is structurally similar to (benzene)ruthenium dichloride dimer.
The dimer is prepared by the reaction of the phellandrene with hydrated ruthenium trichloride. [1] At high temperatures, [(cymene)RuCl22 exchanges with other arenes:
(Cymene)ruthenium dichloride dimer reacts with Lewis bases to give monometallic adducts:
Such monomers adopt pseudo-octahedral piano-stool structures.
Treatment of [(cymene)RuCl22 with the chelating ligand Ts DPENH gives (cymene)Ru(TsDPEN-H), a catalyst for asymmetric transfer hydrogenation. [2]
[(cymene)RuCl22 is also used to prepare catalysts (by monomerization with dppf) used in borrowing hydrogen catalysis, [3] a catalytic reaction that is based on the activation of alcohols towards nucleophilic attack.
It can also used to prepare other ruthenium—arene complexes. [4]
