Аннотация:
Novel calix[4]pyridine with four 2-thioxido-1,3,2-dioxaphosphorinane fragments attached to aromatic substituents was prepared by one-step condensation of 2,6-dihydroxypyridine hydrochloride with para-thiophosphorylated benzaldehyde. To improve the solubility of the obtained compound, O-benzoylation of its hydroxyl groups was implemented.
