Abstract

resumo hidrogenação de dienos com complexos de ródio sob atmosfera livre de monóxido de carbono. a presente invenção refere-se ao campo de hidrogenação catalítica e, mais particularmente, a um processo para a redução por hidrogenação, utilizando-se h2 molecular, um dieno conjugado c6-c20 num enal desconjugado correspondente, caracterizado pelo fato de que o referido processo é realizado na presença de um sistema catalítico compreendendo pelo menos uma base e pelo menos um complexo na forma de um complexo de ródio que compreende um ligante bidentado de difosfina c34-c60 (l2), que coordena o ródio.
