Spirocyclic 2,5-dihydro-1H-imidazole 1-oxyl radicals with a mesogenic substituent on C4. Synthesis and crystal structure
摘要:
Stable spirocyclic 2,5-dihydro-1H-imidazole 1-oxyl radicals containing a mesogenic fragment were synthesized on the basis of 1-[4-hydroxy(alkoxy)phenyl]-2-hydroxyamino-2-methylpropan-1-ones. The crystalline structure of two aminoxyl radicals was determined by X-ray analysis.

New non-conjugated functionalized 2,5-dihydroimidazole-type biand trinitroxyl radicals are described. The synthesis of which was based on a nucleophilic substitution reaction between 2,4,6-trichloro-1,3,5-triazine or 2,4-dichloro-6-methoxy-1,3,5-triazine and spiro-fused 2,5-dihydroimidazole-type monoradicals bearing both a p-hydroxyaryl moiety at the C-4 atom of the heterocycle and a residue at the
