摘要

A new series of hydrocarbon cages containing hexa-and Octacoordinate carbon centers were designed theoretically by performing DFT calculations at the B3LYP/6-311 + G** level.Among these non-classical structures that were found to still obey the 8e rule,the two tetracations with Octacoordinate carbons may be the first examples found in pure hydrocarbons.Structural characteristics,as well as thermodynamic and kinetic stabilities,were also investigated theoretically for these two Octacoordinate tetracations.These hydrocarbon compounds containing hypercoordinate carbon centers provide a challenge for synthetic organic chemists.
