摘要: Resume La synthese d'alkylphosphonates a longues chaines hydrocarbonees est ici presentee. Ces composes sont obtenus par addition d'alkylmercaptans sur des allyl- et vinylphosphonates. Pour la de monoadduits desires, les allyliques plus interessants que vinyliques. Nous avons ensuite envisage leur modification chimique en vue d'obtenir monoacides diacides phosphoniques selon deux voies: soit hydrolyse acide ou basique, silylation. Cette seconde voie implique tout d'abord dealkylation l'ester phosphone un halogenure trimethylsilane, le bromotrimethylsilane ou, moins efficace mais economique, chlorotrimethylsilane, puis l'hydrolyse silyle obtenu.
