摘要:2,5-Dioxo-1,2-oxa-phospholanes of the formula (I) ##STR1## wherein R 1 is an organic radical and R 2 and R 3 each also represents an organic radical or hydrogen, are prepared by reacting 2-haloformylethyl-phosphinic acid halides of the formula (II) ##STR2## wherein R 1 , R 2 and R 3 are defined as in formula (I) and X means Cl or Br, preferably Cl, with an approximatey equimolar quantity of acrylic acid. The compounds (II) may also be produced in the reaction batch and in situ by reacting about equimolar quantities of a dihalophosphine of the formula (III) ##STR3## with an α,β-unsaturated acid (IV) n n R.sup.4 -- OH (IV) n n In the formulae (III) and (IV) R 1 , R 2 , R 3 and X are defined as indicated above. n In the reaction there is formed, in addition to the compounds (I), practically exclusively β-halopropionic acid and no free hydrogen halide. n The phospholanes (I) are valuable flame retarding agents for plastics, intermediates, for example, for the synthesis of biocidals etc.
