Synthesis of Hydroxylamine Derivatives. I : Mannich Reaction with Substituted Hydroxylamine

Four-Component Reaction between Ethyl Benzoylacetate, Hydroxylamine, Aldehydes and Malononitrile: Synthesis of Isoxazol-5(2H)-Ones

We present herein a new and efficient four-component synthesis of isoxazol-5(2H)-ones involving ring closing/Knoevenagel condensation/Michael addition sequential reactions.

The reaction of acetylcholine and other carboxylic acid derivatives with hydroxylamine, and its analytical application.

In spite of its physiological importance acetylcholine has been determinable chemically only after isolation by time-consuming procedures. Of necessity workers in this field have resorted to pharmacological bioassays whose specificity seems open to doubt. The finding that choline is readily acetylated by the action of a coenzyme-linked enzyme system in which adenosine triphosphate serves as an ...

Potential for the use of hydroxylamine derivatives as wood preservatives

Conventional wood preservatives have provided excellent protection against wood-degrading organisms; however, increasing public mistrust of these chemicals has encouraged a search for alternative wood protection strategies that take advantage of the physiological capabilities of the target organisms. One approach is to use chelators to sequester elements required by fungi to initiate the decay ...

Determination of Hydroxylamine and Its Derivatives in Pharmaceuticals Using Spectrophotometry

On the basicity of hydroxylamine and its derivatives

The рКа. values of hydroxylamine and its derivatives were determined titrimetrically in water and water — ethanol mixtures. The obtained püCa values of the O-alkylhydroxylamines were correlated with the half-wave potentials of the Polarographie reduction waves. A surprisingly high pi£a value of hydroxylamine was explained on the basis of the formation of hydrogen bonds with solvent proved by me...
