Abstract Tungstosilicicacid was found to be an efficient catalyst for the synthesis of trisphenols using the reaction of 2,6-bis(hydroxymethyl)phenols with phenols in an aqueous medium. The catalytic reactivity of tungstosilicicacid in boiling water was examined with a series of substrates, demonstrating that this catalyst is reactive in the presence of a variety of functionalities.

pH unit–1 at 37 °C. Here, we demonstrate through a series of CF3-functionalized CoII2 complexes [(XL′)Co2(etidronate)]− (X = NO2, F, Me), that modest changes in the electronic structure of CoII centers through remote ligand substitution can significantly affect the NMR and CEST properties of Co2-based PARACEST probes. Variable-pH NMR and CEST analyses reveal that the chemical shifts of the ligand protons
我们报告了三个新的基于Co 2的顺磁化学交换饱和转移(PARACEST)探针,能够按比例定量pH值。Co II 2络合物[LCo 2(etidronate )] -,具有四(羧酰胺)和OH取代的依替膦酸酯配体,具有相反的pH依赖性CEST峰强度,先前已显示出log(CEST OH / CEST)之间呈线性相关NH)和pH在6.5-7.6范围内,在37°C时灵敏度为0.99(7)pH单位–1。在这里,我们通过一系列CF 3官能化的Co II 2配合物[(X L')Co2(etidronate)] -(X = NO 2,F,Me),通过远距离配体取代而引起的Co II中心电子结构的适度变化会显着影响基于Co 2的PARACEST探针的NMR和CEST特性。可变pH NMR和CEST分析表明,配体质子的化学位移受X取代基的性质高度影响。对于X = NO 2,F和Me,分别在115和88、93和79以及88和76

Alcohols and phenols are efficiently nitrated with thionylchloride nitrate or thionyl nitrate, even in the presence of an aromatic moiety. While thionylchloride nitrate is suitable for nitration of primary OH-groups in carbohydrates, thionyl nitrate is reactive enough to react with secondary OH-groups as well. These reagents permit the highly selective nitration of the 5′-,2′5′- and 3′, 5′-OH-groups
即使在存在芳族部分的情况下,醇和苯酚也可以被硝酸亚硫酰氯或硝酸亚硫酰有效地硝化。硝酸亚硫酰氯适用于碳水化合物中伯羟基的硝化,而硝酸亚硫酰具有足够的反应性,可以与仲羟基反应。这些试剂允许核糖核苷的5'-,2'5'-和3',5'-OH-基团的高选择性硝化,以高产率产生单保护或双保护的硝基衍生物。碳酸和某些酮的烯醇形式可以用三氟甲磺酰硝酸盐/叔丁醇钾有效地硝化。Lutidine N -oxide(2,6-(CH 3)2 C 5 H 3发现NO)对硝化反应具有显着影响。类似地,亚硫酰氯亚硝酸盐和亚硫酰亚硝酸盐显示出优异的上述底物的亚硝化能力。
Solvent-free synthesis of trisphenols as starting precursors for the synthesis of calix[4]arenes using sulfonated multi-walled carbon nanotubes
enols (BMP) (6 examples) is reported using sulfonated multi-walled carbon nanotubes (SO3H@MWCNTs) under solvent-free conditions as starting precursors for the synthesis of macrocyclic molecules of calix[4]arenes. The new protocol provides a series of trisphenol derivatives (21 examples) in high yields (up to 94%) and relatively short reaction times (15–120 min). Also, directsynthesis of calix[4]arenes
据报道,在无溶剂条件下使用磺化多壁碳纳米管(SO 3 H @ MWCNTs)作为苯酚衍生物(12种底物)与2,6-双(羟甲基)苯酚(BMP)的缩合(6个实例)用于合成杯[4]芳烃的大环分子。该新方案以高收率(高达94%)和相对较短的反应时间(15-120分钟)提供了一系列三酚衍生物(21个实例)。另外,已有报道通过使用催化剂由不同的三酚直接合成杯[4]芳烃(5个实例)。此外,合成的杯[4]芳烃是通过一锅法从简单易得的原料(如p)获得的。-甲酚合成5,11,17,23-四甲基杯[4]芳烃-25,26,27,28-四醇。同样,在此过程中,SO 3 H @ MWCNTs可以以几乎一致的效率重复使用七次,并且可以通过简单的过滤回收。
