Abstract
1. UN PROCESO PARA PREPARAR UN COMPLEJO DE METAL QUE CONTIENE UNO Y SOLO UN GRUPO PI-LIGADO DESLO- CALIZADO, CICLICO, DICHO COMPLEJO QUE CORRESPONDE A LA FORMULA: FIGURA 1 EN DONDE M, ES TITANIO O ZIRCONIO EN EL ESTADO DE OXIDACION FORMAL +2; L ES UN GRUPO QUE CONTIENE UN PI-SISTEMA ANIONICO, DESLOCALIZADO, CICLICO A TRAVES DEL CUAL EL GRUPO ESTA LIGADO A M, Y CUYO GRUPO ESTA TAMBIEN UNIDO A Z; Z ES UNA TRAZA UNIDA A M POR VIA DE UN ENLACE O, QUE COMPRENDEN BORO, O UN MIEMBRO DEL GRUPO 14 DE LA TABLA PERIODICA DE LOS ELEMENTOS, Y TAMBIEN COMPRENDE NITROGENO, FOSFORO, AZUFRE, U OXIGENO, DICHA TRAZA TIENE HASTA 60 ATOMOS DIFERENTES A HIDROGENO. X ES UN DIENO CONJUGADO NEUTRAL, OPCIONALMENTE SUSTITUIDO CON UNO O MAS GRUPOS HIDROCARBILO, DI- CHA X TIENE HASTA 40 ATOMOS DE CARBONO Y FORMAN UN PI-COMPLEJO CON M; X´ ES UNA BASE LEWIS NEUTRA LIGANTE SELECCIONADA DE AMINAS, Y ETERES, DICHA X´ TIENE DE 3 A 20 ATO- MOS DIFERENTES A HIDROGENO; Y n ES UN NUMERO QUE VA DE O a 3. DICHO PROCESO COMPRENDE PONER EN CONTACTO UN COM- PUESTO DE HALURO DE METAL DE ACUERDO CON LA FORMU- LA: FIGURA 2 EN DONDE, M* ES TITANIO O ZIRCONIO EN EL ESTADO DE OXIDACION FORMA +3; M** ES TITANIO O ZIRCONIO EN EL ESTADO DE OXIDA- CION FORMA +4; X* ES ALURO; Y L, Z, X´ Y n SON COMO SE DEFINIO PREVIAMENTE; CON UN DIENO LIBRE QUE CORRESPONDE A X, Y SUBSE- CUENTEMENTE O SIMULTANEAMENTE ENTRA EN CONTACTO CON LA MEZCLA DE REACCION RESULTANTE CON UN DERI- VADO DE GRIGNARD DE UN PI-ALKANO DE 1 A 20 CARBO- NOS PARA FORMAR LOS COMPLEJOS DE METAL DESEADOS.
