✦ Synopsis


We have found that 1,3-dipolar additions to 3,3-dimethylcyclopropene sometimes give rearranged products, but the rearrangement products all derive from a normal 1,3-dipolar adduct.

Wo products from 3,3-dimethylcyclopropene or methylenecyclopropane' additions have been found that would correspond to a cyclopropyl to ally1 rearrangement of an intermediate in a stepwise addition.

With longer-chain carbonamides, partial isomerization occurs. For example, crotonamide yields 68 % a-methylsuccinimide and 19 % glutarimide. Alicyclic unsaturated carbonamides form bicyclic imides. 0 II Cyclohexenecarbonamide forms hexahydrophthalimide in 91 % yield.
