Abstract
Un método mejorado para convertir un óxido de fosfina terciaria en la correspondiente fosfina terciaria, por reacción del óxido de fosfina con un compuesto de silicio que contiene la estructura SiHX, en la que X es halógeno, en presencia de una cantidad estequiométrica de una amina, en el que la mejora que consiste en seleccionar la amina del grupo que consta de aminas primarias y secundarias monofuncionales y polifuncionales.
