One-Pot Ozonolytic Synthesis of Isoniazid Derivatives from (–)-α-Pinene and Δ<Superscript>3</Superscript>-Carene

Optically active isoniazid derivatives containing a cyclopropane or cyclobutane fragment have been synthesized by ozonolysis of (+)-Δ³-carene and (–)-α-pinene, followed by treatment of the ozonolysis products with isonicotinic acid hydrazide.     

Transformations of peroxide olefin ozonolysis products under the action of hydroxylamine and semicarbazide hydrochlorides in isopropyl alcohol

Hydroxylamine and semicarbazide hydrochlorides were shown to be efficient as reducing agents toward peroxide products of ozonolysis of various olefins with different degrees of substitution. The rate of the transformations aldehyde → aldehyde oxime → nitrile → ester upon treatment of peroxides with hydroxylamine hydrochloride in isopropyl alcohol was lower than in methanol.     

Transformations of peroxide olefin ozonolysis products in methanol in the presence of water

Transformations of peroxide products of ozonolysis of various olefins with different degrees of substitution at the double bond by the action of hydroxylamine and semicarbazide hydrochloride in methanol in the presence of water as co-solvent were studied.     

The Influence of Ultrafine-Grained State of Zr – 1 wt.% Nb and Ti – 45 wt.% Nb Alloys on their Thermophysical Properties and Energy Dissipation and Accumulation during Deformation

Russian Physics Journal - The results of a study of thermal conductivity and specific heat capacity of Zr – 1 wt.% Nb and Ti – 45 wt.% Nb alloys in coarse-grained and ultrafine-grained...     

Ozonolysis of alkenes and study of reactions of polyfunctional compounds: LXVIII. Investigation of transformations of peroxide products of olefins ozonolysis treated with hydroxylamine hydrochloride

Hydroxylamine hydrochloride efficiently reduces peroxide products of olefins ozonolysis into carbonyl compounds. Depending on the substrate character, solvent, and the treatment conditions the arising aldehydes transformed along the route aldehyde→aldoxime→nitrile→ester into individual compounds or their mixtures, or give the corresponding acetals.     

Transformations of peroxide products of olefin ozonolysis under the action of semicarbazide in methanol

Peroxide products generated by ozonolysis of non-1-ene, 3-carene, stereoisomeric ??-pinenes, (?)-limonene, and castor oil were subjected to transformations by the action of semicarbazide and hydrazine-1,2-dicarboxamide in methanol.
