A general procedure for Te-alkylated tellurolesters synthesis is reported.The carbonyl i.r. frequencies and 13C chemical shifts of these compounds are compared to the O, S, and Se analogs.The origin of the electronic interaction between the carbonyl group and the heteroatom is shown to depend on this latter nature: whereas a combination of both inductive and mesomeric effects is to be taken into account for O.This effect is mainly inductive for Se and Te.In the case of S-compounds, no such a simple model can be involved.The reason of which might be the participation of the 3d-orbitals to the electronic system.Moreover, the prev iously reported Te heavy atom effet has been detected on the α methylene groups exclusively.
