Description
3 Предмет изобретени Способ получени алкпловых эфиров а-диалкоксифосфинилацетоуксусных кислот О соов l,nU;.,-г где R и R - алкил Ci-€4, отличаюидййс тем, что, с целью повышени выхода нелевого продукта, соответствуюн;ий диалкокси-а- 15 4 окси-а - карбоалкоксндиазаметилэтилфосфонат общей формулы v О CH-j lRO)2-P-i-C-c:oOB он , где R и R- вышеуказанные значени , подвергают термическому разложению при температуре не выше кипени диоксана до прекращени выделени азота с последующим выделением целевого продукта известными приемами.3 The subject of the invention. Method for the preparation of α-dialkoxyphosphinyl acetoacetic acid alkyl esters O soy l, nU ;, - g where R and R are C 4 alkyl, differing in that in order to increase the yield of the non-neutral product corresponding to their dialkoxy - 15 4 hydroxy-a - carboalkoxydiazamethylethylphosphonate of the general formula v O CH-j lRO) 2-PiCc: oOB it, where R and R are the above values, are subjected to thermal decomposition at a temperature not higher than boiling of dioxane until the evolution of nitrogen stops, followed by separation of the target product famous tricks.
