The complexes cis- and trans-RuII(dppm)2Cl2 (dppm = Ph2PCH2PPh2) have been found to undergo isomerization reactions induced by light, heat, or oxidation to Ru(III). The conversion trans → c

Isomerically pure nitrile complexes cis-[Ru(dppm)2Cl(NCR)]+ (2a-d) are formed upon chloride displacement from cis-[Ru(dppm)2Cl2] (1) or, alternatively, by ligand substitution from the acetonitrile complex 2a. This latter approach does also allow for the introduction of pyridine (3a,b), heptamethyldisilazane (4) or isonitrile ligands (5). All complexes are obtained as the configurationally stable cis-isomers. Only cis-[Ru(dppm)2Cl(CNtBu)]+ slowly isomerizes to the trans from. The solid state structures of the CH3CN, C2H5CN and the trans-tBuNC complexes were established by X-ray crystallography. Electrochemical investigations of the nitrile complexes 2a-d show in addition to a chemically reversible one-electron oxidation an irrversible reduction step. In CH2Cl2 solution, cis-and trans-[Ru(dppm)2Cl2] have been identified as the final products of the electrochemically induced reaction sequence.
