77Se NMR. 2. The Basis for Application of JSe-Se and JSe-H in Structure Assignments of Mono-, Di-, and Triseleno-Substituted Alkenes

Article abstract of DOI:10.1021/jo00360a005

Series of isomeric mono-, di-, and triseleno-substituted alkenes have been synthesized and subjected to 77Se NMR analysis.In di- and triseleno-substituted alkenes stereochemical assignments were obtained by measurements of 77Se-77Se coupling constants.Val
