long chain dithiooxamides which in some cases show a different behaviour with respect to R 2 H 2 DTO bearing small substituents on nitrogen atoms. The observed reactivity appears related only in part to the lower basicity of amide nitrogen atoms in diaryl- with respect to dialkyl-dithiooxamides, and differently populated conformations of the complexes seem to play an important role. Mesophase formation
摘要为寻找具有成矿作用的仲二硫代草酰胺(RNHCS)2(RNHCS)2(称为R 2 H 2 DTO)铂配合物,从顺式[[Pt(Me 2 SO)]合成了数种[Pt(R 2 HDTO)2]。 )2 Cl 2]。本文主要研究长链二硫代草酰胺的配位化学,在某些情况下,该配位化学相对于在氮原子上带有小取代基的R 2 H 2 DTO表现出不同的行为。相对于二烷基-二硫代草酰胺,观察到的反应性似乎仅部分与二芳基中酰胺氮原子的碱性较低有关,并且配合物的不同填充构象似乎起重要作用。R = 3,4- [CH 3(CH 2)9 O] 2 C 6 H 3和3的[Pt(R 2 HDTO)2]的中间相形成,通过偏振光学显微镜和差示扫描量热法提出了4- [CH 3(CH 2)11 O] 2 C 6 H 3的建议。还描述了类似的双螯合物的合成,但是具有两个不同的二硫代草酰胺配体。
