How intramolecular coordination bonding (ICB) controls the homolysis of the C-ON bond in alkoxyamines.

ABSTRACT: Because the C-ON bond homolysis rate constant k _d is an essential parameter of alkoxyamine reactivity, it is especially important to tune k _d without a major alteration of the structure of the molecule. Recently, several approaches have become known, e.g., protonation of functional groups and formation of metal complexes. In this paper, coordination reactions of [Zn(hfac)₂(H₂O)₂] with a series of new SG1-based alkoxyamines affording complexes with different structures are presented. The k _d values of the complexed forms of the alkoxyamines were compared to those of free and protonated ones to reveal the contribution of the electron-withdrawing property and structure stabilization.
