Preparation of Polymer-Bound Dinitrogen Complexes by Direct Reactions of Polymer–Metal Complexes with Molecular Nitrogen

Polymer-bound dinitrogen complexes were synthesized directly from the polymer-bound (η5-vinylmethylcyclopentadienyl)tricarbonylmanganese analogues and molecular nitrogen in tetrahydrofuran (THF)/benzene (1:5 v/v) under 3 atm of N2 at 2°C. Dinitrogen complexes were also prepared by the oxidation of the hydrazine coordinated to the polymer-bound manganese complexes with hydrogen peroxide in the presence of cupric ions. The polymer-bound dinitrogen complexes are considerably stable compared to that of the corresponding monomer model of (η5-methylcyclopentadienyl)dicarbonyldinitrogenmanganese.
