Planar conjugated ketones having a ring larger than a seven membered one are potentially interesting macrocycles, because these compounds are expected to be aromatic if they contain a (4n+3) membered ring and nonaromatic if they contain a (4n+l) membered ring. To these compounds, F. Sondheimer') pro
