N-(Aminoethyl)cyclam: A Tetraaza Macrocycle with a Coordinating Tail (Scorpiand). Acidity Controlled Coordination of the Side Chain to Nickel(II) and Nickel(III) Cations

Article abstract of DOI:10.1021/ja00251a016

The novel functionalized macrocycle N-(aminoethyl)cyclam (4, L), in which a NH2CH2CH2-chain is appended to a tetraaza ring, has been prepared through a convenient route, whose key step involves the reaction of tritosylated cyclam and tosylaziridine.The ni
