Abstract

original image

Doppelter Einsatz: Eine Verbindung, in der eine Permethylzirconocen-Einheit über eine Oxobrücke mit einem Erdalkalimetall-Fragment verbrückt ist, wurde hergestellt. Mit diesem Heterodimetallkatalysator wurde eine Reihe primärer und sekundärer Aminoalkene zu cyclischen Produkten umgesetzt. Das Calciumzentrum aktiviert dabei die primären Aminoalkene und das Zirconiumzentrum die sekundären.
