Complete 1 H, 13 C, and 125 Te NMR spectral data for some vinyl tellurides are described. The 1 H– 125 Te g HMBC 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. Copyright © 2012 John Wiley & Sons, Ltd.
