Treatment of [RuCl(PP3iPr)]+Cl- (PP3iPr = P(CH2CH2P iPr2)3) with hydrazine, phenylhydrazine, and methylhydrazine afforded side-on bound hydrazine complexes [RuCl(η 2-H2N-NH2)(η3-PP 3iPr)]+, [RuCl(η2-H 2N-NHPh)(η3-PP3iPr)] +, and [RuCl(η2-H2N-NHMe) (η3-PP3iPr)]+. The analogous reactions of [RuCl2(PP3Ph)] (PP 3Ph = P(CH2CH2PPh2) 3) with hydrazine, phenylhydrazine, and methylhydrazine afforded end-on bound hydrazine complexes [RuCl(η1-H2N-NH 2)(PP3Ph)]+, [RuCl(η 1-H2N-NHPh)(PP3Ph)]+, and [RuCl(η1-H2N-NHMe)(PP3Ph)] +. Treatment of parent hydrazine complex [RuCl(N2H 4)(PP3iPr)]+ with strong base afforded the dinitrogen and dihydride complexes [Ru(N2)(PP 3iPr)] and [RuH2(PP3 iPr)]. Treatment of phenylhydrazine complex [RuCl(NH 2NHPh)(PP3iPr)]+ with strong base afforded the hydrido ruthenaindazole complex [RuH(η2-NHi? - ?NC6H4)(η3-PP3iPr)] while similar treatment of methylhydrazine complex [RuCl(NH2NHMe) (PP3iPr)]+ afforded the hydrido methylenehydrazide complex [RuH(NHNi? - ?CH2)(PP 3iPr)]. Treatment of the hydrazine complexes [RuCl(NH 2NHR)(PP3Ph)]+ (R = H, Ph, Me) with strong base afforded the dinitrogen complex [Ru(N2)(PP 3Ph)].
