By six examples, it was demonstrated that nitrosylsulfuric acid can be successfully used for oxidation of 3,5-diaryl-4,5-dihydroisoxazoles to the corresponding 3,5-diarylisoxazoles. If the starting isoxazolines contain the aromatic substituents activated towards electrophilic substitution, nitration of both newly formed isoxazole and substituted benzene rings occurred. 相似文献

Nanocomposite macromolecular systems consisting of silver nanoparticles immobilized in a carboxymethyl chitin matrix are obtained. The method of ultrasonic treatment of a heterophase system (isooctane-water) in the presence of antioxidants of plant origin is used to transfer silver nanoparticles from their micellar solution in isooctane to an aqueous polymer solution. The formation of hydrogen bonds between the functional groups of carboxymethyl chitin and hydroxyl groups of antioxidants is confirmed by Fourier transform infrared spectroscopy. This interaction can provide additional stabilization of metal nanoparticles in the macromolecular system. The transmission electron microscopy data shows that the size of silver nanoparticles increases in a series of antioxidants (gallic acid, dihydroquercetin, and syringic acid). The increase is presumably caused by significant differences in the structures of these antioxidants and their interaction with the polymer matrix. 相似文献

A new technique is described that makes it possible to detect reaction products with the escape of charged particles occurring on components of working gas under the action of fast neutrons. This technique is unique since it offers the possibility of studying reactions for which more than two charged particles are generated in an output channel. This work studies interactions between neutrons and 10B nuclei, where two α-particles and tritium nucleus are produced as reaction products. 相似文献
