摘要

The synthesis of the highly strained title compound 8a was achieved by the valence isomerization and in situ dehydrogenation of the cyclophanediene 7a at only 80 deg C. A single-crystal X-ray structure determination of 8a revealed that the pyrene moiety is remarkably bent, the two ends forming an angle of 109.2 deg. This degree of lengthwise bend slightly exceeds that present in the pyrene unit found in the equator of D_(5h) C_(70), rendering it the most bent pyrene group yet prepared. The expectation of unusual reactivity is borne out by the apparent Diels-Alder reaction between 8a and tetracyanoethylene (TCNE) to give adduct 9.
