PHOSPHORIC ACID ESTERS, AMIDES, AND ANHYDRIDES 339 Reaction between phosphoric acids and carboxylic acids yields the phosphoric acid-carboxylic acid anhydrides, XLIV, essentially

Lack of kynurenic acid (KYNA, 4-hydroxyquinoline-2-carboxylic acid) effect on the hyperpolarization-activated cation current (I h ) recorded from GH 3 cells.. The whole-cell

Thus, aldehydes, ketones, acid halides, anhydrides esters, and carboxylic acids are reduced to alcohols, nitriles and acid amides to amines (the latter also to alcohols in

[5] Performing temperature dependent infrared and photoluminescence investigations I found evidence for chemical transformation of carboxylic groups to acid anhydride groups on

In this study we investigate the adsorption efficiency of the styrene-6.7%divinylbenzene copolymer functionalized with carboxylic acid groups (SDVB-F) for the

The synthesized [Fe III (SALEN)Cl], [Cu II (AA) 2 ] and the bpy containing cyclic and acyclic amino acid complexes appeared to be active and selective catalysts in the

34 Progress has been related to use of triblock polymers synthesized with controlled concentrations of carboxylic acid binding groups in central polyurethane segments and

Transformation of coumarin (COU) and coumarin-3-carboxylic acid (3-CCA), the formation of their fluorescent hydroxylated products, (7-hydroxy-coumarin (7-HO-COU) and

On the other hand, the concentration of the samples taken from the aqueous phase might strongly increase by the addition of the carboxylic acid batches, and the equivalent volume of

The infrared spectra of the polymers formed in the liquid and solid phases are shown in Fig. Thus, structures of the polymers formed by the irradiation of norbornene carboxylic

Humic acid is negatively charged even at low pH due to the dis- sociation of its acidic (mainly carboxylic and phenolic hydroxyl) groups [1,17,18]. Humate polyanions can be

On the other hand, the concentration of the samples taken from the aqueous phase, might strongly increase by the addition of the carboxylic acid batches, and the equivalent volume

The mixture was refluxed for 10 h, the reaction mixture was then evaporated and the oily product was crystallized from n-hexane and recrystallized from iPr 2 O-EtOAc.. The

The third KC in both the English group and the Chinese group was 'incompatibility of existing construction pattern and robot application', which concerned that the need of

We describe a selective and environmentally friendly CF acetylation of aromatic and aliphatic amines by the use of a low-cost and environmentally friendly Lewis acid catalyst as

The group deals with the synthesis of organosilicon compounds which are expected to have biologi- cal activity, with the investigation of their structure and

T h e method proceeds from the dimethyl ether of resorcinol, which can be metalated on the 2-carbon atom with phenyllithium, according to Wittig ( 5 7 ). T h e condensation goes
