MeOH. On treatment of 3 with an equimolar amount of ethanol. [VVO(OEt)L2] (5b) is obtained. With the chiral tertiary bis(ethanol)amine (S)- or (R)-(HOCH2CH2)2NCH(Ph)Me, H2L3, [VO(acac)2] loses only one acetylacetonate (1-) ligand, and the complexes (S)- and (R)-[VVO(acac)L3] (6a) are formed. As is evident for the corresponding reaction with (HOCH2CH2)2NPh, H2L4, which affords [VVO(acac)L4 (6b), the
硫酸氧钒与衍生自邻香兰素的席夫碱H 2 L 1和甘氨酸反应生成[V IV O(H 2 O)L 1(1),用乙酰氯处理可得到顺-[V IV Cl 2 L 1 ](2)。[VO(acac)2 ]与衍生于邻羟基萘甲醛和邻羟基苯胺的席夫碱H 2 L 2在有氧条件下反应产生[V V O(L 2)} 2μ-O](3),在过量的甲醇中进行甲醇分解以形成[V V O(MeOH)(OMe)L 2 ](5a)。复杂的图5a也通过[V获得V OCL(L 2)](4)和MeOH。用等摩尔量的乙醇处理3时,[V V OCl(L 2)](4)和MeOH。用等摩尔量的乙醇处理3。获得[V V O(OEt)L 2 ](5b)。与手性叔双(乙醇)胺(S)-或(R)-(HOCH2 CH 2)2 NCH(Ph)Me,H 2 L 3,[VO(acac)2 ]仅失去一个乙酰丙酮酯(1-)配体,以及配合物(S)-和(R)-[V V
