Abstract

(1)(2) synthesis has recently been achieved,'was found by NMR spectroscopic investigations to be a nonplanar olefinic molecule, 2 having the double bonds arranged around the periphery of the two fused eight-membered rings and experiencing a degenerate n-bond shift3 In view of its double-bond configuration, octalene can be derived from Sondheimer's [14] annulene (2) 4 by connecting carbon atoms 1 and 8, and thus, in a ...
