Abstract

LA PRESENTE INVENCION SE DIRIGE A UN PROCESO PARA LA PREPARACION DEL REACTIVO DIMETIL TITANOCENE (CP 2 TI(CH 3 ) 2 ) A PARTIR DEL DICLORURO DE TITANOCENE (CP 2 TICL SUB,2 ) Y UN HALURO DE METIL MAGNESIO, EN PARTICULAR CLORURO DE METIL MAGNESIO (CH 3 MGCL). EL PROCESO INSTANTANEO APORTA EL REACTIVO DESEADO DE MANERA QUE ES GENERALMENTE MENOS PELIGROSO Y MAS ECONOMICO QUE METODOS PREVIOS.
