The reaction of 1,1-diacyclopropanes with methylenephosphorane in the presence of dimsylsodium in DMSO leads to 1,1-bisalkenyl- and 1,1-alkenylacylcyclopropanes, depending on the ratio of the reagents.In the case of cyclopropylidenephosphorane it leads exclusively to spirocyclopropanecyclooctatrienes.
