In the structure of the title complex salt, (Et2NH2)2[CuCl4], the asymmetric unit consists of four unique di-ethyl-ammonium cations and three unique tetra-chlorido-cuprate anions. Two of the three anions are located with their copper atoms on independent crystallographic twofold axes, while the remaining tetra-chlorido-cuprate is located at a general position of the ortho-rhom-bic space group P...

Many steps in the analysis of rough and semirough endotoxins were found to be facilitated by the use of isobutyric acid-ammonium hydroxide solvent.

The title compound, {[Zn2(CH3CO2)3(OH)(C6H7ClN2)]·C2H5OH} n , has alternating octa-hedrally and tetra-hedrally coordinated Zn(2+) ions. The octa-hedral coordination sphere is composed of one N atom of the monodentate di-amino-chloro-benzene ligand, three acetate O atoms and two bridging hydroxide ligands. The tetra-hedral coordination sphere consists of three acetate O atoms and the hydroxide l...

Starting from commercially available educts, a straightforward synthetic route to new heterocyclic building blocks is exemplified with the one- or two-step synthesis of tri-, tetra-, or pentacyclic ring systems. Representatives of the following novel ring systems are prepared from 3-methyl-1-phenyl-2-pyrazolin-5-one and the corresponding o-halo-arenecarbonyl chloride using calcium hydroxide in ...

Abstract A series of new quinazoline-4(3H)-one derivatives (2-16) have been synthesized using methyl α-[(4-oxoquinazolin-2-yl)thio]acetate (1) as precursor. The corresponding hydrazide (2) and thiosemicarbazide (4) were from this ester via the reaction with hydrazine hydrate ammonium thiocyanate respectively. was employed to synthesize 2-amino-1,3,4-thiadiazole (5) 1,3,4-triazole-5-thiol (6) it...

(9S,13S,14S)-3-Meth-oxy-17-methyl-morphinan (dextromethorphan) forms two isostructural salts with (a) tetra-chlorido-cobaltate, namely bis-[(9S,13S,14S)-3-meth-oxy-17-methyl-morphinanium] tetra-chlorido-cobaltate, (C18H26NO)2[CoCl4], and (b) tetra-chlorido-cuprate, namely bis-[(9S,13S,14S)-3-meth-oxy-17-methyl-morphinanium] tetra-chlorido-cuprate, (C18H26NO)2[CuCl4]. The distorted tetra-hedral ...

In recent years, there has been a growing interest in green solvents to dissolve and shape cellulose into microspheres. However, development of suitable for room temperature dissolution shaping spheres is very limited. this work, novel process fabricate microspheres presented. First, the effect ethanol-hydrochloric acid pulp pretreatment on solubility aqueous tetra-n‑butyl phosphonium hydroxide...

A recently reported binuclear zinc hydroxide complex [(L(1)Zn(2))(mu-OH)](ClO(4))(2) (, L(1) = 2,6-bis[(bis(2-pyridylmethyl)amino)methyl]-4-methylphenolate monoanion) containing a single bridging hydroxide was examined for thioester hydrolysis reactivity. Treatment of it with hydroxyphenylthioacetic acid S-methyl ester in dry CD(3)CN results in no reaction after approximately 65 h at 45(1) degr...
