Diisopropyl (mercaptomethyl) phosphonate was easily prepared by the reduction of S-methyl phosphonodithioesther with sodium borohydride, heated under reflux of acetonitrile. The phosphonate carbanion generated from the corresponding S-allyl sulfide underwent a [3,2] sigmatropic shift, and led to diisopropyl (allyl mercapto methyl) phosphonate.
