Abstract

The reaction of cis-[RuCl(2)(PP)(2)] (PP = depe, dmpe) with hydrazine afforded end-on bound ruthenium(II) hydrazine complexes. Treatment of the hydrazine complexes with strong base afforded the side-on bound ruthenium(0) diazene complexes cis-[Ru(eta(2)-NH=NH)(PP)(2)]. Treatment of cis-[Ru(eta(2)-NH=NH)(depe)(2)] with weak acid under chloride-free conditions afforded the side-on bound hydrazine complex cis-Ru(eta(2)-N(2)H(4))(depe)(2). These are the first reported side-on bound diazene and hydrazine complexes of ruthenium, and they have been characterized by NMR spectroscopy ((1)H, (31)P, (15)N) and by X-ray crystallography. The interconversion between the ruthenium diazene and the ruthenium hydrazine by acid-base treatment was reversible.

摘要

顺式-[RuCl2(PP)2]（PP = depe，dmpe）与联氨反应生成端接键合的钌（II）联氨配合物。将联氨配合物用强碱处理得到侧接键合的钌（0）二氮烯配合物顺式-[Ru(eta2-NH=NH)(PP)2]。在无氯条件下，用弱酸处理顺式-[Ru(eta2-NH=NH)(depe)2]得到侧接键合的联氨配合物顺式-Ru(eta2-N2H4)(depe)2。这些是首例报道的钌的侧接键合二氮烯和联氨配合物，并用 NMR 光谱（（1）H、（31）P、（15）N）和 X 射线晶体学进行了表征。通过酸碱处理，钌二氮烯和钌联氨之间的互变是可逆的。
