Abstract
Abstract: 1, l-Diphenyl-2-vinylcyclopropane (la) reacts with tetracyanoethylene yielding N- diphenylmethylene-2, 3, 3-tricy-ano-5-vinylcyclopent-1-enylamine (2a) as a major adduct. The related ethylene IC produces fluorenylideneamine 2c and the chain adduct 4a. The expected cycloadducts did not form in both cases. In contrast, the Diels-Alder reaction of la with tetrachlorocyclopentadienone ethylene acetal gives the normal cycloadduct 6c. ...
