Abstract

Procedimiento para la preparación de sales con ácidos dialquil-fosfínicos, caracterizado porque a) se hace reaccionar fósforo amarillo elemental con halogenuros de alquilo en presencia de un hidróxido de metal alcalino o de metal alcalino-térreo para dar una mezcla que, como componentes principales, contiene las sales con los ácidos alquil-fosfonosos, fosforoso e hipofosforoso, b) la mezcla se ajusta a un valor del pH de menos que 7 y luego se hace reaccionar con olefinas en presencia de un agente iniciador de radicales, y c) los ácidos dialquil-fosfínicos obtenidos según la etapa b) y/o sus sales de metales alcalinos se hacen reaccionar con compuestos metálicos de Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na y/o K, para dar las sales de los metales con ácidos dialquil-fosfínicos.
