Theoretical Study on the Stability and Aromaticity of Metallasilapentalynes
Submitted by Jun Zhu on Sat, 03/22/2014 - 11:20Antiaromatic compounds and small cyclic alkynes or carbynes are both challenging for synthetic chemists because of the destabilization caused by their antiaromaticity and highly distorted triple bonds, respectively. These dual destabilizations could be the reason why pentalyne (I), a highly antiaromatic and extremely strained cyclic alkyne, has never been synthesized.
