  日期：——

  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.

  通过氢化物从相关的环庚三烯化合物中提取氢化物，可以得到阳离子对苯二甲酰基咪唑基亚烷基ITrop +的衍生物。光谱，结构和理论数据表明，ITrop +作为苯并咪唑基亚胺的阳离子亲和性，具有高度还原的σ供体和强的π受体特性。
