Differentiation and assignment of vinyl telluride regioisomers by 1H-125Te gHMBC

Complete 1H, 13C, and 125Te NMR spectral data for some vinyl tellurides are described. The 1H–125Te gHMBC experiment was used for the complete chemical shift assignment and structure elucidation of a mixture of regioisomers. The assignment (125Te NMR) and coupling constants (JH,H) for all regioisomers are described for the first time. Copyright © 2012 John Wiley & Sons, Ltd.
