note = "Funding Information: A comparison of the barrier for ring inversion in (2) with the barriers reported for less sterically hindered cyclo-octatetraene derivatives1 is a striking confirmation of our thesis that non-bonded interactions constitute the major source of structural rigidity exhibited by such systems. We thank the National Science Foundation for the support of this research. (Receiued, 6th October 1972; Corn. 1705.) -1 Added $12 pyoof. Independently, A. Rosdshl and J. Sandstrom (Tdvahedron Letters, 1972, 4187) have reported a lower limit to ring inversion of 26 kcal mol-l for another derivative of tetrabenzocyclo-octatetraene. 1Satisfactory elemental and mass spectral analyses were obtained for (2). S.1n.r. spectral data were in agreement with the structure assigned. 1 G. 13. Senkler, jun., D. Gust, P. X. Riccobono, and K. Mislow, J. Awcr. Chcna. SOC.,1972, 94, 8626.
