Abstract

METODO DE PREPARACION DE CATALIZADORES DE HIDROGENACION HOMOGENEOS Y ESTEREO-ESPECIFICOS. CONSISTE EN LA OBTENCION DEL COMPUESTO BIS(TRIFENILFOSFINA)HIDRAZINOMETOXIRODIO, POR REACCION DE CLOROTRIS(TRIFEILFOSFINA)RODIO CON HIDRATO DE HIDRAZINA EN EXCESO DE TRES MOLES DE HIDRAZINA A UNO DE RODIO. LA REACCION SE LLEVA A CABO EN METANOL DESGASIFICADO, EN ATMOSFERA INERTE DE NITROGENO, A LA TEMPERATURA DE REFLUJO DE LA MEZCLA DE REACCION, DURANTE UNOS MINUTOS A DOS HORAS; SEGUIDA DE LA SEPARACION DEL PRODUCTO FORMADO MEDIANTE FILTRACION Y SECADO DEL MISMO EN ATMOSFERA DE NITROGENO. ESTE CATALIZADOR TIENE APLICACIONES PARA LA OBTENCION DE 2-6-DEOXI-5-HIDROXI-TETRACICLINA POR HIDROGENACION DE LA 6-DEMETIL-6-DEOXI-6-METILEN-5-HIDROXITETRACICLINA.
