A novel fast, convenient and inexpensive synthesis of 1′,3′-dioxo-1′,3′-dihydrospiro[cyclopropane-1,2′-indene]-2,2,3,3-tetracarbonitrile and dimethyl 2,3-dicyano-1′,3′-dioxo-1′,3′-dihydrospiro[cyclopropane-1,2′-indene]-2,3-dicarboxylate is reported. These compounds undergo double carbanion cleavage under the action of alcohols resulting in the formation of stable salts, containing new allylic-type
一种新颖,快速,方便且廉价的合成1',3'-dioxo-1',3'-dihydrospiro [cyclopropane-1,2'-indene] -2,2,3,3-tetracarbonitrile和二甲基2,3-报道了二氰基-1',3'-二氧代-1',3'-二氢螺[环丙烷-1,2'-茚] -2,3-二羧酸酯。这些化合物在醇的作用下会经历双碳负离子裂解,从而形成稳定的盐,其中包含新的烯丙基型阴离子,并有可能在有机电子领域中应用并作为离子液体组分。
