This red-coloured, diamagnetic solid is a reagent in organometallic chemistry and homogeneous catalysis. The complex is structurally similar to (benzene)ruthenium dichloride dimer. Preparation and reactions The dimer is prepared by the reaction of the phellandrene with hydrated ruthenium trichloride.Bennett, M. A. Huang, T. N. Matheson, T. W. Smith, A. K.

Precursor to catalysts Treatment of [(cymene)RuCl2]2 with the chelating ligand TsDPENH gives (cymene)Ru(TsDPEN-H), a catalyst for asymmetric transfer hydrogenation.

It can also used to prepare other ruthenium—arene complexes.http://www.thieme-connect.de/DOI/DOI?10.1055/b-003-117830 Category 1, Organometallics: Compounds with Transition Metal—Carbon π-Bonds and Compounds of Groups 10–8 (Ni, Pd, Pt, Co, Rh, Ir, Fe, Ru, Os) 2001 Georg Thieme Verlag 978-3-13-112131-8 Lautens M.
