Abstract
Derivatives of the cationic tropylium annulated imidazolylidene ITrop are obtained by hydride abstraction from related cycloheptatriene compounds. Spectroscopic, structural and theoretical data indicate that, as a cationic relative of benzimidazolylidenes, ITrop has highly reduced σ-donor and strong π-acceptor character.
摘要
通过从相关的环庚三烯化合物中去除氢得到阳离子薁环咪唑啉 ITrop 的衍生物。光谱、结构和理论数据表明，作为苯并咪唑啉的阳离子类似物，ITrop 具有高度降低的 σ-供体和强的 π-受体特性。
