Abstract
Procedimento per la preparazione di N-fosfonometilglicina, mediante ossidazione di acido N-fosfonometilimminodiacetico, con perossido per formare un intermedio di acido N-fosfonometilimminodiacetico-N-ossido e conversione di tale intermedio per dare N-fosfonometilglicina, in cui la conversione di detto intermedio è effettuata mediante addizione di un agente riducente scelto tra metalli del gruppo che consiste di magnesio e selenio o di un composto scelto tra arseniti, idrosolfiti, boroidruri, fosfiti, seleniti, acido fosforoso, acido selenioso e anidride solforosa.
