Аннотация
A series of Zn(hfac)2 alkoxyamines (diethyl(2,2-dimethyl-1-(tert-butyl-(1-pyridylethoxy)amino)propyl)phosphonate) coordinated at ortho, meta and para positions of their pyridyl moiety were prepared and their homolysis rate constants kd measured. Up to a 30-fold increase in kd was observed for the meta-(Zn-RR/SS) and para-(Zn-RR/SS) regioisomers. Moreover, the activation is also controlled by the amount of pyridine, used as a ligand competitor. XRD, 1H and 31P NMR spectra show very different structures for each complexes in solid state and in solution depending on the diastereosiomers and on the regioisomers.
