Abstract

The reaction of lanthanide shift reagents with the heterocyclic analogs of substituted 2'-alkoxychalcones was studied. It was shown that the coordination of Eu(fod)3 and Yb(fod)3 with them takes place in different ways. The former forms mainly adducts of the chelate type with participation of the oxygen atoms of the carbonyl and alkoxyl groups in coordination, while from the latter only the adduct at the carbonyl group is obtained. For this reason it was concluded that there are some limitations to the use of the reagents for conformational analysis of organic compounds. It was shown that they can only be used to study the conformational movements of the molecules not affecting the complexation process.
