Abstract

A series of substituted tetraselenafulvalenes (TSeFs) was studied in solution using ^1^H, ^13^C and ^77^Se NMR spectroscopy. Chemical shifts and heteronuclear coupling constant values were determined and assigned. Novel two‐dimensional H(Se)C and H(C)Se triple‐resonance correlation experiments were applied at natural abundance in order to accomplish ^13^C and ^77^Se signal assignments. Using this approach, all the signals were unambiguously assigned and atom connectivity was established in the studied TSeF derivatives. These experiments, allowing signal assignments of quaternary carbons, may find wide application in the study of substituted TSeF and other organoselenium compounds. To the best of our knowledge, triple‐resonance experiments with proton detection have been applied to organoselenium compounds for the first time. Copyright © 2007 John Wiley & Sons, Ltd.

## Abstract The ^77^Se, ^13^C and ^1^H NMR spectra of the products of phenylselenenyl azide and chloride addition to methylenecyclohexane and cyclohexene are presented. Scalar couplings between ^77^Se and ^1^H/^13^C allowed the absolute assignment of the regioisomers in the ^1^H and ^13^C spectra.
