trans (Cl)‐Ru(bpy)(CO) 2 Cl 2 ( 1 ; bpy = 2,2′‐bipyridine) was found to efficiently isomerize to cis (Cl)‐ 1 in DMSO by addition of a catalytic amount of NaBH 4 , even at room temperature. The isomerization reaction is air sensitive, but does not require photoirradiation. Addition of the Cl – ion remarkably accelerates the reaction. A plausible chain reaction mechanism mediated by the reduced ruthenium dimer and monomer of 1 is proposed for the trans – cis isomerization.
