The perimidine skeleton provides a framework for the isolation of a novel, stable carbene possessing a unique molecular architecture and electronic structure. The remarkable steric environment and exceptional electron-donating ability for the carbene-carbon are revealed through structural and spectroscopic characterization of the parent carbene and two sterically encumbered rhodium-carbene complexes, L2RhCl{C[NCH(CH3)2]2(C10H6)} (5 L2 = COD; 6 L = CO).
嘧啶骨架为分离一种具有独特分子结构和电子结构的新型稳定卡宾提供了一个框架。通过母体卡宾和两种空间位阻较大的铑-卡宾配合物L2RhCl{C[NCH(CH3)2]2(C10H6)}（5 L2 = COD；6 L = CO）的结构和光谱表征，揭示了卡宾碳显著的空间环境和特殊的给电子能力。
