描述了使用新配体 PP(3)(i) (1) P(CH(2)CH(2)P(i)Pr(2))(3) 合成一系列铁和钌配合物的方法。通过处理铁(II)和钌(II)阳离子物种[FeCl(PP(3)(i))](+) (2)和 [RuCl(PP(3)(i))](+) (3) 在氮气气氛下与钾石墨。阳离子二氮物种 [Fe(N(2))H(PP(3)(i))](+) (6) 和 [Ru(N(2))H(PP(3)(i))](+) (7) 分别用 1 当量弱有机酸处理 4 和 5 制备。通过 X 射线晶体学对配合物 2.[BPh(4)]、3.[BPh(4)]、4、5 和 6.[BF(4)] 进行了表征。 5的结构表征是钌(0)二氮配合物的首次报道。
The synthesis of a series of iron and ruthenium complexes with the new ligand PP(3)(i) (1) P(CH(2)CH(2)P(i)Pr(2))(3) is described. The iron(0) and ruthenium(0) dinitrogen complexes Fe(N(2))(PP(3)(i)) (4) and Ru(N(2))(PP(3)(i)) (5) were synthesized by treatment of the iron(II) and ruthenium(II) cationic species [FeCl(PP(3)(i))](+) (2) and [RuCl(PP(3)(i))](+) (3) with potassium graphite under a nitrogen atmosphere. The cationic dinitrogen species [Fe(N(2))H(PP(3)(i))](+) (6) and [Ru(N(2))H(PP(3)(i))](+) (7) were prepared by treatment of 4 and 5, respectively, with 1 equiv of a weak organic acid. Complexes 2. [BPh(4)], 3.[BPh(4)], 4, 5, and 6.[BF(4)] were characterized by X-ray crystallography. The structural characterization of 5 is the first report for a ruthenium(0) dinitrogen complex.
