In this work, the preparation of the first ruthenium complexes containing a phosphino-oxime ligand is presented. Thus, the reaction of cis-[RuCl2(DMSO)4] (3) with 2.4 equivalents of 2-Ph2PC6H4CHNOH (1) in refluxing THF led to the clean formation of the octahedral ruthenium(II) derivative cis,cis,trans-[RuCl2κ2-(P,N)-2-Ph2PC6H4CHNOH}2] (5), whose structure was unambiguously confirmed by means of a
在这项工作中,提出了含有膦-肟配体的第一种钌配合物的制备方法。因此,顺式-[RuCl 2(DMSO)4 ](3)与2.4当量的2-Ph 2 PC 6 H 4 CH NOH(1)在回流THF中的反应导致八面体钌(II)的干净形成。衍生物的顺式,顺式,反式-将[RuCl 2 κ 2 - (P,ñ)-2-PH 2 PC 6 H ^ 4 CHNOH} 2 ](5),其结构通过单晶X射线衍射研究得到明确证实。复杂5也可以由二聚[的RuCl(μ-Cl)的(η的反应合成的6 -对异丙基苯甲烷)} 2 ](4)与过量的1在回流的甲苯中。的治疗4与2个当量的1,在CH 2氯2在室温,也允许的半夹心的Ru(制备II)衍生物将[RuCl κ 2 - (P,Ñ)-2-PH 2 PC 6 ħ4 CHNOH}(η 6 -对异丙基苯甲烷)] [PF 6 ]( 6)。另外,络合物5和6被证明是醛糖肟重排成伯酰胺以及
