Abstract
The design and synthesis, as well as solid state and ESR characterisation o f three new triradicals based on phenyl ethynyl backbone bearing nitronyl-n itroxide and imino-nitroxide groups, are reported. The synthesis of these c ompounds was based on palladium-coupling reactions between alkynyl and brom o derivatives. An ESR study showed magnetic interactions between the radica ls through the phenyl ethynyl-coupling unit in solution. (C) 2000 Published by Elsevier Science Ltd. All rights reserved.
