Dichlorocarbene reacts with the exo dimer of cyclopentadiene (exo-tricyclo2,6>deca-3,8-diene) and the trimer of cyclopentadiene (exo-endo-pentacyclo2,7.09,13>pentadeca-4,10-diene) at the cyclopentene double bond.The Simmons-Smith reagent, prepared from methylene iodide in presence of a zinc-silver couple, reacts with the same hydrocarbons and also with the dimer of spirohepta-4,6-diene 2,6>deca-3,8-diene)-10-spirocyclopropane> nonselectively at both double bonds, whereas it adds to the trimer of cyclopentadiene only at the norbornene double bond.
