Reaction of the [Mo(NO)₂]²⁺ moiety with a suitable ligands is a very convenient method to synthesize different dinitrosylmolybdenum complexes. It was also applied for the synthesis of a new compound of empirical formula Mo(NO)₂(O₂CMe)₂. The reaction of catalyst precursor with EtAlCl₂ was spectroscopically examined (IR in the v(NO) region). Reagent concentrations were as in the metathesis reaction. The reaction between Mo(NO)₂(O₂CMe)₂ and EtAlCl₂ is accompanied by liberation of ethane. During the stable period of the system (decrease in intensity of the bands v(NO) < 1%) one molar equivalent (vs. precursor concentration) of ethane evolved.
