Synthesis of 2-iminonitroxide-substituted phenols and pyridine-3-oles.
摘要:
Methods for the synthesis of a new family of nitronylnitroxides, iminonitroxides, and their precursors with 2-hydroxyphenyl or 3-hydroxypyridin-2-yl substituents in the side chain have been developed. Five heterospin chelates of Cu(II) with deprotonated iminonitroxides have been isolated. Their structure and magnetic properties have been studied. In all complexes, ferromagnetic intramolecular exchange interactions take place (J similar to 40-350 cm(-1)) (C) 2003 Elsevier Science Ltd. All rights reserved.
