Abstract

The fac-LCr (CO) 3 tridentate complexes of 1, 4, 7, 10-tetraazacyclododecane 1, 1, 4, 8, 11- tetraazacyclotetradecane 2, 1, 4, 7, 10-tetraazadecane 3 and 1, 5, 8, 12-tetraazadodecane 4 have been selectively alkylated in high yield at the uncomplexed nitrogen atom, giving rise to mono N-functionalized tetraamines and bis-macrocyclic compounds.
