Anions of allylmeldrum's acids reacted with phenyl(propynyl)iodonium salt to produce bicyclo[3.1.0]hex-1-enes as the reactive intermediates through cyclopropanation reaction to yield various dimerization products. Depending on the substitution pattern on the intermediates, various dimeric products were obtained.

A double bond migration driven by the high strain energy of endocyclic methylenecyclopropane-containing fusedbicyclic systems is proposed to explain the formation of azabicyclo[3.1.0]hexanes from the intramolecular addition of alkylidene carbenes to alkenes.
