Matrix Isolation of 3,4-Benzocyclodeca-3,7,9-triene-1,5-diyne
摘要:
3,4-Benzocyclodeca-3,7,9-triene-1,5-diyne (3) has been synthesized from two different precursors and characterized by means of matrix-isolation spectroscopy. Energies, structures and IR spectra of the product, the intermediate 9,10-didehydroanthracene (4), and of the transition state of the Bergman cyclization 3 --> 4 have been calculated at the B3LYP/6-31G* level of theory.
