Preferential Incorporation of a Cyclopropyl σ Bond Over an Ethylenic π Bond in the TCNE Cycloaddition of 1,2-Dicyclopropylethylene. Occurrence of the Type-II Reaction in Some Disubstituted Substrates
Among the two types of cycloadditions known to take place in the reactions of cyclopropyl-substituted ethylenes (1) with tetracyanoethylene (TCNE) (type-1 gives a cyclobutane derivative (2) and type-II yields a vinylcyclopentane derivative (3), the type-II reaction has been practically limited to occur in reactions of tetrasubstituted substrates. However, some disubstituted substrates, namely cis-
