SYNTHESIS OF DIOLS BEARING PHOSPHONATE GROUPS PART III. THIOLS USED AS STARTING MATERIALS

摘要: This article describes the synthesis of diols bearing a phosphonated group. The method used is monoaddition thiol on unsaturated compounds. Two ways are possible depending species either group or diol function. First we added function onto dialkylallylphosphonates. Then groups was an allylic diol. On other hand compared radical and UV additions. We also reactivity similar compounds (dimethyl diethyl phosphonates). All reactions gave very good yields different products have been analyzed by NMR studies. Finally, succeeded in corresponding phosphonic diacids bromosilane method.
