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.
首次大规模制备的氰基亚甲基环丙烷在几种环加成中被证明是反应性偶极亲和性和亲二烯性的。已经将该化合物的反应性与3-甲基-2-丁烯腈,3-甲基-2-丁烯酸乙酯和乙氧基羰基亚甲基环丙烷进行了比较。
