Procédé de préparation de dérivés d'acétoamides, d'acétothioamides et d'acétosélénoamides, en particulier de dérivés de carbamoylméthylphosphines et carbamoylméthylphosphines ainsi obtenues

A method for preparing acetoamide derivatives by reacting an acetoamide-derived anion, e.g. of formula (I), wherein Z is O, S or Se and R , R , R and R are hydrogen atoms or optionally substituted hydrocarbon groups, with a phosphine, arsine or stibnite halide, e.g. of formula (II), wherein Y is P,...

Beschreibung
Zusammenfassung:A method for preparing acetoamide derivatives by reacting an acetoamide-derived anion, e.g. of formula (I), wherein Z is O, S or Se and R , R , R and R are hydrogen atoms or optionally substituted hydrocarbon groups, with a phosphine, arsine or stibnite halide, e.g. of formula (II), wherein Y is P, As or Sb. A derivative of formula (a) is thereby obtained and may be used to remove lanthanides and actinides from acidic solutions.
