Abstract

HIDROGENAÇÃO DE IMINAS. A presente invenção refere-se a um processo de hidrogenação assimétrica de iminas com hidrogênio sob pressão elevada na presença de um sistema catalítico. A invenção refere-se principalmente ao uso do citado sistema catalítico de hidrogenação enantiosseletiva de cetiminas proquirais a aminas assimétricas levando à formação de herbicidas.
