✦ Synopsis

In the previous paper (1) we have described a two-step synthesis of 1,6-methanaCl0lannulen-1 l-one from tropone. This compound, having the p-orbital of the carbonyl group .approximately perpendicular to the peripheral IOn-electron system, failed to exhibit appreciable n-n interaction between them. We present

Although 1,6-methanoOOJannulene is well known to be aromatic (1), those with trigonol Cl1 provides additional'interesting problem with respect to the intemction of the P, orbital of bridge.and peripheral IOn-electron system. Thus, 11 methylene-1,6-methanoClObnnuIene synthesized by Vogel (2) disclose
