Abstract

Complete (1) H, (13) C, and (125) Te NMR spectral data for some vinyl tellurides are described. The (1) H-(125) Te gHMBC experiment was used for the complete chemical shift assignment and structure elucidation of a mixture of regioisomers. The assignment ((125) Te NMR) and coupling constants (J(H,H) ) for all regioisomers are described for the first time.
