Synthesis and properties of azole-substituted ferrocenes
摘要:
4-Ferrocenyltriazole, 4-(4-ferrocenylphenyl)triazole, 4-ferrocenyltetrazole, and 4-(4-ferrocenylphenyl)tetrazole have been prepared. Redox potentials and decomposition temperatures were evaluated and all the compounds were crystallographically characterized; in most cases, weak intermolecular (CHN)-N-... hydrogen bonds ((HN)-N-... dist. = 2.3-2.5 angstrom) were formed between the azole moieties. Two polymorphs were found for 4-ferrocenyltetrazole, formed with either (CHN)-N-... or pi-pi interactions. (c) 2006 Elsevier B.V. All rights reserved.
