标题:具有手性二硫醚配体的阳离子铱配合物:氢化条件下的合成,表征和反应性
摘要:为了研究硫取代基和金属环尺寸对乙酰氨基丙烯酸酯加氢反应的影响,制备了一系列含有手性二硫醚配体的阳离子 Iri 配合物.在配合物 6,7 和 10 的情况下,由于硫转化过程,在溶液中观测到非对映异构体的混合物.相比之下,通过使用抑制配合物 8 和 9 中 S 反转的双环配体可以有效地控制这种流动行为. 配合物 10B 的固态结构仅显示一种非对映异构体,其中硫取代基处于相对反位和整体scsscssss 在配位的二硫醚配体上的构型.含有七元和六元金属环 (6B-d,7B,C,10A,B) 的铱配合物通过 S-配体取代与底物反应,而这种取代的速率与氟原子在芳环上的位置有关.相反,含有双金属环(8 和 9)的配合物不会被底物置换.根据相应二氢化物配合物(13和14)的高稳定性分析配合物8和9的催化氢化活性.在这两种情况下,四种可能的非对映二氢化物物质中只有两种在溶液中形成.(© Wiley-Vch

摘要:The invention relates to the synthesis of tetraphenol-substituted structures, in particular meta-substituted xylenes. Said tetraphenol-type structures are reacted to obtain organic phosphorus compounds, in particular organophosphites. The invention further relates to the production of catalytically active compositions which contain transition metals in addition to the aforementioned organic phosphorus compounds. According to another subject matter of the invention, said catalytically active compositions are used in chemical reactions with small molecules, e.g. HCN, CO, hydrogen, and amines.

摘要:A method for producing alcoxylated carbonyl compounds of general formula (I) (compounds I): R<1>aR<2>C(OR<3>)b wherein R<1>, R<2 >represent hydrogen or C1-C6-alkyl, R<3 >independently means C1-C6-alkyl, a is 0 or 1, b 2 or 3 with the proviso that the sum of a and b is 3, by means of anodic oxidation of germinal dialcoxy compounds of general formula (II) (compounds II) wherein R<4>, R<5>, R<6>, R<7 >represent hydrogen or C1-C6-alkyl, R<5>, R<6 >represent C1-C6-alkyl or C1-C6-alcoxy, in the presence of a C1-C6-alkyl alcohol (compounds III). A usual compound (compound IV) is used as a cathodic depolarizer suitable for electrochemical oxidation. The anodic oxidation and cathodic reduction is carried out in an undivided electrolyte cell in the presence of C1-C6-alkyl alcohols.
