New synthetic routes to hexa-aza cages using cobalt(III) tris(1,2-diamine) templates

Abstract

A synthetic route to form hexa-aza macropentacyclic Cobalt(III) complexes was discussed. The encapsulation reaction was carried out using a non-aqueous synthetic methodology in which formaldehyde derived from solid polymer was used to generate coordinated methamines by reaction with deprotonated primary amines of the template. The analysis showed that the cage complex retains the δ-absolute configuration of the template iron. Show more
