A new approach to stabilize compounds containing a planar tetracoordinate carbon (ptC), embedded in aromatic hydrocarbons, is presented herein. This is achieved by using ligands that promote the formation of a 3c-2e σ-bond with the ptC under two conditions: without altering the sp hybridization of the aromatic carbons; and containing empty orbitals perpendicular to the aromatic ring to participate in the aromatic π-electronic delocalization.
本文提出了一种稳定嵌入芳烃中的平面四配位碳（ptC）化合物的新方法。这是通过使用配体来实现的，该配体在两种条件下促进与ptC形成3c-2e σ键：不改变芳族碳的sp杂化；并且含有垂直于芳环的空轨道以参与芳族π电子离域。
