The reactions of 1,1-dichloro-2,3,4,5-tetraphenyl-1-germacyclopenta-2,4-diene (1), magnesium, and R3ECl (E = Si, Ge) under mild conditions (20 °C, THF) gave 1,1-bis(trimethylsilyl)-2,3,4,5-tetraphenyl-1-germacyclopenta-2,-4-diene (2a) and 1,1-bis(triethylgermyl)-2,3,4,5-tetraphenyl-1-germacyclopenta-2,4-diene (2b) respectively. The reaction is versatile and applies to the compounds R3ECl (E = Si, Ge) that do not react with magnesium.
在温和条件下(20 °C,THF),1,1-二氯-2,3,4,5-四苯基-1-锗杂环戊-2,4-二烯(1)、镁和 R3ECl(E = Si,Ge)反应生成 1、1-双(三甲基硅基)-2,3,4,5-四苯基-1-锗杂环戊-2,-4-二烯 (2a) 和 1,1-双(三乙基锗基)-2,3,4,5-四苯基-1-锗杂环戊-2,4-二烯 (2b)。该反应用途广泛,适用于不与镁反应的化合物 R3ECl(E = Si、Ge)。
