Abstract

UV spectroscopy is used to study the kinetics of formation of 5-benzylideneazolidones-4. The reaction is shown to be irreversible and follows a second-order equation. The effect of various hetero atoms (sulfur, nitrogen, and oxygen) in position 1 or 2 on the methylene group reactivity of azolidones-4 is investigated. The azolidones-4 fall into two series with respect to decreasing activity of the group in acetic acid in the presence of anhydrous sodium acetate: rhodanine>2-thiohydantoin>pseudo-thiohydantoin>glycocyamidine> thiazolidinedione-2, 4>2 -thionoxazolidone-4>hydantoin>pseudo-hydantoin>oxazolidinedione-2, 4.
