Abstract

There has been considerable interest in the properties of fused (4n+ 4 n)~ networks. Although their predicted stability is intermediate between aromatic and antiaromatic networks, 2 the few known examples appear to have physical properties characteristic of polyolefins. We wish to report the preparation of the first example of a hydrocarbon containing an (8+ 4)~ network that shows definite antiaromatic properties. 1 ...
