摘要：

Complete 1H, 13C, and 125Te NMR spectral data for some vinyl tellurides are described. The 1H125Te 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 (C) 2012 John Wiley & Sons, Ltd.
