In this research, a kind of nonwoven composite used for the absorption of heavy mental ions has been made. The composite was made of two layers of ES thermal bonded nonwovens as the protective layers and the PAN-amidoxime nanofibers which are prepared through the modification of electrospun PAN nanofibers as the interlayer. The composition was achieved

Metal Derivatives of Amidoximes. Synthesis of O-(Trimethylsilyl)-N-(trialkylstannyl)amidoximes
Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1977Abstract A few mixed O-(trimethylsilyl)-N-(trialkylstannyl)amidoximes, R(R'3SnNH)-C[dbnd]NO·SiMe3 (where R = Me, Et, Pr or Ph and R' = Me or Bun), have been synthesized by the reaction of lithium derivatives of O-(trimethylsilyl)amidoxines with trialkyltin chlorides in n-hexane under a dry-nitrogen atmosphere.

Some hydroxyamidines and amidoximes
Australian Journal of Chemistry, 1976A number of hydroxyamidines and amidoximes have been prepared in order to examine if their chelating system can lead to cytotoxic compounds. Most compounds are toxic but all are inactive against experimental tumours. The i.r., u.v. and N.M.R. spectra of the hydroxyamidines are discussed.

Rearrangement of phosphylated amidoximes
Journal of the Chemical Society D: Chemical Communications, 1971Phosphorylated benzamidoximes undergo the Tiemann rearrangement in alkaline solution whereas the phosphinylated amidoxime hydrolyses rapidly, and the phosphonylated amidoxime undergoes an intramolecular rearrangement with simultaneous dealkylation.

Amidoxim‐Nachbargruppen in Cyclodehydrierungsreaktionen
Chemische Berichte, 1992Amide Oxime Functions as Neighbouring Groups in Cyclodehydrogenation ReactionsDehydrogenation of the o‐(tertiary amino)benzamide oximes 4, which are monosubstituted at the amide N atom of the neighbouring group, by the mercury edta complex yields tricyclic amino nitrones 9 with a quinazoline 3‐oxide moiety or lactams 8. Product formation depends on the

Selectivity of Amidoxime Polymers for the Sorption of Gallate
Separation Science and Technology, 1995Abstract The sorption of gallium from alkaline solution using amidoxime resins or polyampholytes was studied. Gallium is extracted by amidoxime resins, even from Bayer leachates, but amidoxime polyampholytes are limited to dilute alkali hydroxide solution up to 5 M. The elution of gallium runs well with acetylacetone.

Application of amidoximes for the heterocycles synthesis
Tetrahedron Letters, 2020Abstract In heterocyclic chemistry, amidoximes are mostly known as precursors for the synthesis of 1,2,4-oxadiazoles. Indeed, most of the works related to the use of amidoximes in the synthesis of heterocycles are devoted to 1,2,4-oxadiazoles. Nevertheless, such an artificial narrowing of the scope of heterocyclic systems that can be obtained through

Microwave-Assisted Preparations of Amidrazones and Amidoximes
The Journal of Organic Chemistry, 2006In an operationally straightforward and efficient method, amidrazones and amidoximes are prepared in yields of 65-87% from imidoylbenzotriazoles by microwave heating for 5-20 min with the appropriate hydrazine or hydroxylamine.

How Amidoximate Binds the Uranyl Cation
Inorganic Chemistry, 2012This study identifies how the amidoximate anion, AO, interacts with the uranyl cation, UO(2)(2+). Density functional theory calculations have been used to evaluate possible binding motifs in a series of [UO(2)(AO)(x)(OH(2))(y)](2-x) (x = 1-3) complexes.
