Abstract

SE DESCRIBE UN PROCESO PARA LA PRODUCCION DE TETRAHIDRONAFTALENOS POLIALQUILOS DONDE SE PRODUCE UNA REACCION DE CICLIALQUILACION ENTRE UN COMPUESTO OLEFINICO DE FORMULA GENERAL (I), DONDE R4,R5,R6 Y R7 SON INDEPENDIENTEMENTE DEFINIDOS Y CADA UNO ES UN SUSTITUYENTE QUE NO INTERFIERE SUSTANCIALMENTE CON LA REACCION FRIEDEL-CRAFTS, Y UN COMPUESTO DE BENZONA SUSTITUIDO. EL PROCESO SE LLEVA A CABO EN PRESENCIA DE UN HALIDO ALQUILO O EN ALGUNAS EXPRESIONES, HALIDO HIDROGENO, UN ACIDO LEWIS Y UN AGENTE DE TRANSFERENCIA DE FASE. EN ALGUNAS EXPRESIONES, EL PROCESO SUJETO SE LLEVA A CABO ESPECIFICAMENTE EN AUSENCIA DE UNA IODINA ELEMENTAL. EL PROCESO, QUE PUEDE PRACTICARSE EN UN DISOLVENTE DE HIDROCARBONO NO-HALOGENADO, PRODUCE LOS COMPUESTOS DESEADOS SORPRENDENTEMENTE DE GRAN RIQUEZA, ALTA SELECTIVIDAD Y MEJOR INDICE DE REACCION, UTILIZANDO UNA METODOLOGIA MAS CONVENIENTE Y MENOS CARA QUE MUCHOS PROCESOS YA CONOCIDOS.
