一般說明

丁基异氰酸酯与磷杂环丙烯发生 [2 + 2] 环加成反应生成 1-氧杂-2-基环丁烷 。它还与二氧钼 (芳氧基)配合物发生环加成反应,生成新型的 16 电子钼氧亚胺 (芳氧基)配合物 。微量水存在下与二氢铝反应生成末端氢氧化铝

應用

丁基异氰酸酯可用于:
  • 制备异氰酸酯处理的石墨氧化物 ( i GOs),可在极性非质子溶剂中进行剥离,得到氧化石墨烯纳米片。
  • 对金属有机骨架进行后综合修饰,得到微孔尿素功能化骨架。
  • 以二氢铝为原料合成末端氢氧化铝。

Phosphagermaallene Tip(tBu)Ge=C=PMes* 1 (Tip=2,4,6-triisopropylphenyl, Mes*=2,4,6-tri-tert-butylphenyl) reacts with phenyl isocyanate and tert-butyl isocyanate by a [2+2] cycloaddition that involves the Ge=C and C=O double bonds to afford 1-oxa-2-germacyclobutanes 2 and 3. With N,N'-dicyclohexylcarbodiimide, a [2+2] cycloaddition is observed between the Ge=C
