By reaction of calix[4]resorcinarene with 2-ethyl-1,3,2-benzoxazaphospholine in 1:1 ratio we prepared a cavitand possessing one dioxaphosphocinic fragment on the upper circle of the molecule. Reaction of the same compounds in ether solution in 1:4 and 1:8 ratio according to the data of spectral methods leads initially to formation of addition product, the P-H phosphorane with composition 1:4. This compound is not stable and on keeping forms 2-oxo-2-ethyl-1,3,2-benzoxazaphospholine, spirophosphorane, o-aminophenol and phosphorylated calixarene. In the reaction of the aminoalkylated calixarene with 2-ethyl-1,3,2-benzoxazaphospholine we isolated a compound possessing four hydrophoshonyl fragments on the upper circle of the calixarene matrix. 相似文献

Modification of tetramethylcalix[4]resorcinol with dimethylaminomethyl and 3,5-di-tert-butyl-4-hydroxybenzyl fragments was studied. The antioxidative activity of these macrocyclic stabilizers in rubber stocks based on butadiene-acrylonitrile rubber was examined. 相似文献

A composite for the extraction of lanthanide ions from strongly acidic media by temperature-induced phase separation was designed
based on the nonionic surfactant Triton X-100 and new phosphine oxide derivatives. The dependence of the efficiency and selectivity
of micellar extraction on the length of the hydrophobic substituent at the P=O group is determined by both the influence of
hydrophobic substituents on the electron-donor capacity of the P=O group and the solubility of phosphine oxides in aqueous
and micellar phases. The nitric acid concentration was found to influence the efficiency of extraction of lanthanide ions
by phosphine oxides with different structures. An increase in the concentration of nitric acid in an aqueous medium from 0.1
to 1 mol L−1 leads to a decrease in the degree of extraction by water-soluble derivatives and a substantial increase in the degree of
extraction by phosphine oxides, which are soluble only in the micellar phase of Triton X-100. 相似文献
