L. Catala et al., Synthesis of nitronyl- and imino-nitroxide-triradicals interconnected by phenyl ethynyl spacer, TETRAHEDR L, 41(7), 2000, pp. 1015-1018
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
