  摘要：

  式为##STR1##的2-氧代-2-烷氧基-5-二烷基膦酸酯-1,2-氧杂膦环可以由α,β-不饱和酮和2个或更多个二烷基膦酸酯制备。显然，γ-酮膦酸酯是该反应的中间体，因为这些化合物与1个或更多个二烷基膦酸酯反应也能产生氧杂膦环。两种反应都由碱性催化剂促进。新的氧杂膦环衍生物在热分解方面相当稳定。它们可以用作环氧树脂的阻燃剂。

  2-Oxo-2-alkoxy-5-dialkylphosphono-1,2-oxaphos-pholanes of the formula ##STR1## in which R.sub.1 to R.sub.7 are hydrocarbon radicals can be prepared from .alpha., .beta.-unsaturated ketones and 2 or more moles of a dialkyl phosphite. Obviously .beta.-ketophosphonates are intermediates of this reaction as these compounds react with 1 or more moles of dialkyl phosphite in yielding the oxaphospholanes too. Both reactions are promoted by alkaline catalysts. The new oxaphospholane derivatives are considerably stable against thermal decomposition. They can be used as flame retardants in epoxy resins.

  2-Oxo-2-alkoxy-5-dialkylphosphono-1,2-oxaphospholanes of the formula ##STR1## in which R.sub.1 to R.sub.7 are hydrocarbon radicals can be prepared from .alpha.,.beta.-unsaturated ketones and 2 or more moles of a dialkyl phosphite. Obviously .gamma.-ketophosphonates are intermediates of this reaction, as these compounds react with 1 or more moles of dialkyl phosphite in yielding the oxaphospholanes too. Both reactions are promoted by alkaline catalysts. The new oxaphospholane derivatives are considerably stable against thermal decomposition. They are compatible with polymeric materials and can be used as flame protecting agent for plastics and resins, for example, in polyurethane foams.
