Reduction of Dinitrogen to Ammonia and Hydrazine on Low-Valent Ruthenium Complexes

The ruthenium(0) dinitrogen complexes [Ru­(N2)­(PP3 R)] [PP3 R = P­(CH2CH2PR2)3; R = i Pr or Cy] react with triflic acid and other strong acids to afford mixtures of ammonia and hydrazine. In this reaction, Ru(0) is oxidized to Ru­(II), and depending on the solvent, Ru­(II) benzene or triflate compl...

Description
Summary:The ruthenium(0) dinitrogen complexes [Ru­(N2)­(PP3 R)] [PP3 R = P­(CH2CH2PR2)3; R = i Pr or Cy] react with triflic acid and other strong acids to afford mixtures of ammonia and hydrazine. In this reaction, Ru(0) is oxidized to Ru­(II), and depending on the solvent, Ru­(II) benzene or triflate complexes are isolated and characterized from the reactions with triflic acid as the final metal-containing products from the reaction. The Ru­(II) products are isolated and reduced back to Ru(0) dinitrogen complexes providing a cycle for the reduction of coordinated dinitrogen.
