摘要

In a typical experiment, a mixture of the xanthate and 2 or more equivalents of the olefin in cyclohexane were degassed under argon for 30 min at reflux, then lauroyl peroxide was added in small portions (2% mol) every two hours. The reaction is monitored by thin layer chromatography for completion. The resulting adduct was purified, after evaporation of the solvent, by silica gel chromatography. ... Selected spectral data: 11c: 1 H NMR (CDCl 3 ): δ 7.48-7.38 (m, 5H); ...
