phosphonodithioformates leads to stabilized phosphonium ylids. The reaction of these ylids with hydrochloric acid, methyl iodide, benzyi-, allyl- and propargyl- bromide is studied: C-Protonation or S-alkylation which occurs with an Arbuzov-type dealkylation gives access to substituted methylene bis-phosphonates or to stabilized sulphonium ylids.
