摘要

Various new 2-substituted 4, 4, 5, 5-tetramethyl-4, 5-dihydro-1H-imid-azol-1-yloxyl 3-oxide mono-lb, 7, 13a, b, 14, 15, 16, 17, 22 and biradicals 8, 9 were prepared. The nitronyl nitroxide functions were selectively reduced by Fe/HOAc to 1-hydroxyimidazoline deriva- tives 3b, 11, 21. The reductions by Zn/HCl led to imidazolines 4, 12. The nitronyl nitroxide functions remained inert when the 2-phenyl compound was nitrated by HZSO “/HNO3 to ...
