Abstract
EL INVENTO CONSISTE EN EL DESCUBRIMIENTO DE US PROCESO PARA PROADUCIR TETRAHIDRO NAFTALINAS POLIALQUIL EN DONDE SE LLEVA A CABO UNA REACCION DE CIDIALQUILACION ENTRE UN COMPUESTO OLEFINICO DE FORMULA GENERAL $ Y UN COMPUESTO SUSTITUIDO DE BENCENO, EN PRESENCIA DE UN REAGENTE HIDRURO ABSTRATEGENTE, UN ACIDO DE LEWIS Y OPCIONALEMNTE UN AGENTE DE PASE DE TRANSFERENCIA. EN ALGUNOS ENTORNOS, EL PROCESO OBJETO ES ESPECIFICAMENTE LLEVADO A CABO EN AUSENCIA DE IODINA ELEMENTAL. EL PROCESO OBJETO, QUE PUEDE SER PRACTICADO EN UN SOLVENTE NO HALOGENADO DE HIDROCARBURO, PRODUCE LOS COMPUESTOS DESEADOS UN RENDIMIENTO SORPRENDENTMENTE ALTO, CON UNA SELECTIVIDAD ALTA PARA EL PRODUCTO DESEADO, Y UNA TASA RELATIVAMENTE ALTA DE REACCION, USANDO UN PROCESO METODOLOGICAMENTE MEJOR, MAS CONVENIENTE O MAS BARATO QUE MUCHOS DE LOS PROCESOS CONOCIDOS HASTA AHORA.
