Abstract: | Calculations of the electronic structure of 5-alkyl-2-thiopyrrolidones and their oxygen analogs were carried out by the MO LCAO method in the CNDO/2 approximation. The obtained data were used to discuss the reactivity of the investigated compounds in the alkylation of monochloroacetic acid, leading, in the case of 2-thiopyrrolidones, to the formation of the corresponding thiazolinones.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1690–1692, December, 1986. |
