羧酸衍生物的半还原 传统的合成方法中,从羧酸衍生物(酰氯,酯,酰胺,腈)制备醛的过程通常包括2步反应:先完全还原,然后再氧化。 而羧酸衍生物的半还原(部分还原,Partial reductions)则是合成醛更为直接的方法。其中,最为大家所熟知的试剂就是二异丁基氢化铝DIBALH。该试剂由于其方便的商业可获得性和价格优势,备受...
Ion-transfer parameters of aqueous hydrochloric acid over a wide molality range have been re-investigated taking the concurrent solventtransfer into due account. In this context, the transference numbers for the hydrogen ion τ H and for water τ w have been determined from 10 2 to 15 mol-kg...

Cordyceps sinensis is a medicinal mushroom used for centuries in Asian countries as a health supplement and tonic. Hirsutella sinensis—the anamorphic, mycelial form of C. sinensis—possesses similar properties and is increasingly used as a health supple
Upon completion of the reaction, the organic layer was washed with saturated NaHCO3 (3 × 20 mL), 1 M aqueous HCl (3 × 20 mL) and water (3 × 20 mL) then dried over Na2SO4. The solvent was removed in vacuo and the crude products 11a–e were purified by column chromatography ...
ion sensing has been developed using an ensemble of an indicator, such as 7-hydroxy-4-methylcoumarin (7H4MC) and bromothymol blue (BTB), and a receptor, such as N,N-bis(p-methoxybenzyl)-3,6-dioxaoctane-1,8-diamines (bis-pMDODA) and cryptand [2.2.2] (C222), in aqueous solution....
