Abstract

Analysis of the scientific literature shows that data on nitrogenous derivatives of ketoaldehyde and ketoesters, their synthesis, tautomerization and Complexing ability are incomplete, in some cases their coordination compounds remain abstract, which requires special attention. As a result of the study of the electronic and spatial structures of the complex molecules, it became possible to determine the causes of the "composition-structure-properties" relationship of chemical compounds in a much more complex structure. The structure and tautomerization of para-exchange acylgases of ethyl ether of 2,4-dioxopentanoic acid in various solvents are studied in the article. role of Stephen Krashen's ideas in the theory of second language learning.
