Abstract
We report the preparation of multi-component molecules based on pyridine-, bipyridine- and pyrene-substituted nitronyl nitroxide (NIT) radicals. The s ynthetic protocol is based on a Pd(0) promoted cross-coupling reaction betw een 6-BrPyNIT and either 6-HC drop CPyNIT, diethynyl substituted bipyridine s, or 1-ethynylpyrene derivatives. The magnetic properties and X-ray struct ures of the pyridine (Py) and pyrene-based bi- and monoradicals are describ ed briefly. (C) 1999 Published by Elsevier Science Ltd. All rights reserved .
