Abstract

Procedimiento para la preparación de fosfonitas de las fórmulas generales I y II **(Fórmula)** donde R1 y R2 significan, independientemente uno de otro, un radical de hidrocarbono, eventualmente substituido, o halógeno, x e y son, independientemente uno de otro, 0, 1, 2 ó 3, R3 y R5 son, independientemente uno de otro, hidrógeno o un radical de hidrocarbono, eventualmente substituido. R4 es hidrógeno, un radical de hidrocarbono, eventualmente substituido, -CO-X-R6, -PO-(OR8)2 o -OR8, donde X es -O- o -NR7-, R6 y R7 son, independientemente uno de otro, hidrógeno o un radical de hidrocarbono, eventualmente substituido, R8 es un radical de hidrocarbono, eventualmente substituido, aunque no todos los tres radicales R3, R4 y R5 son hidrógeno al mismo tiempo y en el caso de ser R3 y R5 iguales a butilo terciario, R4 no es metilo; y R9 es hidrógeno.
