Cyanomethylene cyclopropane, prepared for the first time on large scale, proved to be a reactive dipolarophile and dienophile in several cycloadditions. The reactivity of this compound has been compared with 3-methyl-2-butenenitrile, ethyl 3-methyl-2-butenoate and ethoxycarbonylmethylene cyclopropane.
