摘要
This work presents the first detailed study on a series of cyclic hydrocarbon enediynes showing that the cyclization barrier depends upon the ground state energy differences of the biradical products, and that pure density functional methods can be used reliably to estimate the activation enthalpies of the Bergman reaction.
