    CPC classification number: C07F9/42

    Abstract: ALKYPHOSPHONOTHIOIC DIHALIDES ARE PREPARED IN IMPROVED YIELDS BY REACTING AN ALKYL ALUMINUM SESQUIHALIDE WITH A THIOPHOSPHORYL HALIDE IN THE ABSENCE OF A HYDROCARBON SOLVENT. THE REACTION NEED NOT BE CARRIED OUT WITH PURE THIOPHOSPHORYL HALIDE. INSTEAD, THE THIOPHOSPHORYL HALIDE CAN BE IN THE MIXTURE PRODUCED BY REACTING POSPHOROUS TRIHALIDE AND SULFUR WITH AN ALUMINUM TRIHALIDE CATALYST.

    Abstract: Alkylphosphonothioic dihalides are prepared in improved yields by reacting a trialkyl aluminum with a thiophosphoryl halide in the absence of a hydrocarbon solvent. The reaction need not be carried out with pure thiophosphoryl halide. Instead, the thiophosphoryl halide can be in the mixture produced by reacting phosphorus trihalide and sulfur with an aluminum trihalide catalyst.

    Abstract translation: 通过在不存在烃溶剂的情况下使三烷基铝与硫代磷酰卤反应，以提高的产率制备烷基磷硫代二卤化物。 该反应不需要用纯硫代磷酰卤进行。 相反，硫代磷酰卤可以在通过使三卤化磷和硫与三卤化铝催化剂反应制备的混合物中。
