The kinetic studies of cis to trans isomerization of (S)‐1 a demonstrated that the formation of a chiral supramolecule enhances the stability of the cis‐azobenzene structure. The ESI mass spectrum of stilbenedicarboxylic acid (S)‐4, an analogue of (S)‐1 b, confirmed the formation of a dimer. A theoretical CD study revealed that (S)‐1 a in the cis form should be present as a cyclic chiral dimer.
This invention relates to a pharmaceutical composition comprising a Fc receptor modulating compound and a pharmaceutically acceptable carrier. The present invention also relates to a method for treating a variety of diseases using a Fc receptor modulating compound.
We have synthesised and characterised the two possible isomers of heteroleptic trigonal antiprismatic M12L6L′6 MOPs by screening reactions of rhodium acetate with different pairs of complementary dicarboxylate linkers. The resulting 12 new MOPs (eight of isomer A + four of isomer B) are microporous in the solid state, exhibiting Brunauer–Emmett–Teller (BET) surface areas as high as 770 m2 g−1.
我们通过筛选醋酸铑与不同对互补二羧酸酯接头的反应,合成并表征了杂配三角反棱柱 M 12 L 6 L' 6 MOPs 的两种可能异构体。得到的 12 种新的 MOP(8 个异构体 A + 4 个异构体 B)在固态下是微孔的,其 Brunauer-Emmett-Teller (BET) 表面积高达 770 m 2 g -1。

A process is provided for producing an enriched carboxylic acid compositions produced by contacting composition comprising a carboxylic acid with an enrichment feed in an enrichment zone to form an enriched carboxylic acid composition. This invention also relates to a process and the resulting compositions for removing catalyst from a carboxylic acid composition to produce a post catalyst removal composition.
