  描述：

  4,4'-methylaminoethane-1,2-diylbis(2,2,5,5-tetramethyl-2,5-dihydro-1H-imidazole-1-oxyl) 在 potassium carbonate 、 硫酸二甲酯 作用下， 以 丙酮 为溶剂， 反应 336000.0h， 以80%的产率得到4,4'-vinylenebis(2,2,5,5-tetramethyl-2,5-dihydro-1H-imidazole-1-oxyl)

  摘要：

  The reactions of the dianion generated from 1-hydroxy-2,2,4,5,5-pentamethyl-2,5-dihydro-1H-imidazole under the action of lithium diisopropylamide with nitroxyl radicals derived from 2,5-dihydro-1H-imidazole or 2,5-dihydro-1H-imidazole 3-oxide and containing the ester, aldehydo, cyano, or imino groups afforded biradicals, including those containing the enamino ketone and enamino imine functions. The reactions of this dianion with nitriles derived from 2,5-dihydro-1H-imidazole 3-oxide gave rise to all enamino nitrile, i.e., electrophilic cyanation formally occurred.
