The synthesis of a well-defined dicopper carbene complex supported by the PNNP (2,7-bis(di-tert-butylphosphaneyl)methyl-1,8-naphthyridine) expanded pincer ligand is reported. This carbene complex is remarkably stable, even in the presence of air and water. The reactivity of this complex was explored towards typical carbene transfer substrates and its electronic structure was investigated. Using a combination of experiments and DFT calculations, the principles that underly the stability of dinuclear carbene complexes are probed.
报道了一种由PNNP（2,7-双（二叔丁基膦基）甲基-1,8-萘啶）扩展钳形配体支撑的结构明确的二铜卡宾配合物的合成。即使在空气和水存在的情况下，这种卡宾配合物也非常稳定。研究了该配合物对典型卡宾转移底物的反应性，并研究了其电子结构。通过结合实验和密度泛函理论计算，探究了双核卡宾配合物稳定性的潜在原理。
