ß-nitro xanthates as olefin precursors
Abstract
(Matrix presented) Potassium O-ethyl xanthate readily adds to a,ß-unsaturated nitro compounds to give stable ß-nitro xanthates, which undergo tin-free elimination to form olefins in good yield and good E selectivity upon simple heating with lauroyl peroxide in refluxing 1,2-dichloroethane.
