Se estandarizan las condiciones para la elaboración del eterato de trifluoruro de boro, BF3. Et20(l). A partir de (I) se obtienen los diferentes aducios, de trifluoruro de boro con aminas primarias y terciarias, empleados en la síntesis
de B,B',B" - t r i f l u o r o - N , N ' , N " - t r i a r i l (o trialquil) borazinas, ( - B F - N R - ) 3 (II), donde R = Fenil, o - t o l u i l , p—toluil, terbutil. La reacción de obtención de (II) consiste en la deshidrofluoración del aducto BFo—amina primaria por el aducto de impedimento BF3—Amina terciaria, teniendo en cuenta su relación estequiométrica dentro del sistema. Las B—trifluoro borazinas se analizan por espectroscopias IR, UV, y RMN H, análisis elemental y crioscopia.
Mediante el empleo del mismo tipo de reacción, se intenta la obtención de polímeros entrecruzados (III) por enlazamiento con diaminas.
