Description
Verfahren zur Herstellung von neutralen Estern der Thiophosphorsäure In der Patentschrift 818 352 Ist ein Verfahren zur Herstellung von neutralen Estern der Thiophosphorsäure beschrieben, das darin besteht, daß man auf die Al!kaliisalze von Dialkylphosphiten Alkylrbodandde einwirken läßt.Process for the preparation of neutral esters of thiophosphoric acid In patent specification 818 352 is a process for the preparation of neutral esters the thiophosphoric acid described, which consists in the fact that one on the alkali metal salts from dialkyl phosphites alkylrbodandde to act.
Es wurde nun gefunden, daß neutrale Ester der Thiophosphorsäure leicht
zugängh-Ch sind, wenn man, Alkylrlhodanide mit Triralkylphbsph,iten umsetzt. Die
Umsetzung erfolgt bei erhöhter Temperatur, gegebenenfalls in einem indifferenten
Lösungs@mnttel. Auf diese Weise wird bei der Herstellung der gewünschten Thiopihosphors,äu-reester
das Arbeiten mit Alkalimetallen, insbesondere metallischem Natrium, vermieden. Der
Umsetzung liegt folgendes Reaktionsschema zugrunde
Beispiel 1 17 g Triäthylphosphit werden in 3o ccm Xylol gelöst. Unter Rühren gibt
man bei 11d° 14,7 9
ß-Äthy lmercapto-äthylrr!hodanid ;hinzu und entfernt gleichzeitig
das Wärmebad. Die Temperatur steigt von selbst auf 14o°'. Man riihrt bei dieser
