The dinuclear complexes [( p ‐cymene)RuCl 2 ] 2 and [(cyclopentadienyl)MCl 2 ] 2 (M = Ru, Rh, Ir) are important starting materials in organometallic chemistry. The standard synthesis of these complexes involves heating of an alcoholic solution of Ru III , Rh III , or Ir III salts with precursors of the π‐ligands for several hours under reflux. Microwave heating allows these complexes to be obtained within a few minutes without compromising the yields. Furthermore, the microwave‐assisted syntheses require less solvent and, in some cases, lower amounts of ligand precursors.
