Organische Phosphorverbindungen XXVIII. Die α-Aminoalkylierung von elementarem weissem Phosphor. Eine einfache Methode zur Darstellung von tertiären Phosphinoxiden,Phosphinsäuren und Phosphonsäuren [1]

White phosphorus reacts with N-hydroxymethyl-dialkylamines to give mainly three products, i.e., tris(dialkylaminomethyl) phosphine oxides, bis(dialkylamino-methyl) phosphinic acids, and dialkylaminomethyl phosphonic acids, according to the equation: The yield of the various products depends mainly upon the ratio of the reactants, the pH, and the solvents used.
