Reactivity patterns of charged delocalized six-membered chelate rings; N-alkylation, deacylation, and protonation

Abstract

Reactivity patterns paralleling those found for transition metal corrole complexes are reported for a nickel(II) 15-membered macrocyclic complex containing charged delocalized six-membered chelate rings; N-alkylation of the nitrogen donor atoms as well as deacylation and reversible protonation of the meso-carbon atoms of such rings have been observed, and the resultant N-alkyl groups are reactive, being solvolysed in nucleophilic solvents.
