Abstract

Starting from paramagnetic β-bromo-α,β-unsaturated aldehyde 1, β-bromo-α,β-unsaturated nitrile 2 and diene 3 heterocycles 4-10 and carbocycles 12-14, 16, and 17 were synthesized with simple procedures in the presence of a nitroxide moiety. A complex-forming paramagnetic phenanthroline 19 is also described.

Key words

Diels-Alder reaction - free radicals - heterocycles - ligands - polycycles
