Mixed-ligands hydride complexes [RuHCl(CO)(PPh3)2{P(OR)3}] (2) (R = Me, Et) were prepared by allowing [RuHCl(CO)(PPh3)3] (1) to react with an excess of phosphites P(OR)3 in refluxing benzene. Treatment of hydrides 2 first with triflic acid and next with an excess of hydrazine afforded hydrazine complexes [RuCl(CO)(κ1-NH2NHR1)(PPh3)2{P(OR)3}]BPh4 (3, 4) (R1 = H, CH3). Diethylcyanamide derivatives [RuCl(CO)(N≡CNEt2)(PPh3)2{P(OR)3}]BPh4 (5) were also prepared by reacting 2 first with HOTf and then with N≡CNEt2. The complexes were characterized spectroscopically and by X-ray crystal structure determination of [RuHCl(CO)(PPh3)2{P(OEt)3}] (2b).
