制备
四甲基碘化铵可由三甲胺和碘甲烷的气相反应生成。[3]甲醇、碘甲烷和28%氨溶液反应,[4]或者N,N-二甲基甲酰胺和碘甲烷在25%的碱溶液(氨、氢氧化钠或氢氧化钾)中反应,都可以得到该季铵盐。[5]
结构
四甲基碘化铵属四方晶系,空间群P4/nmm,晶胞参数a=7.9643 Å, b=5.7550 Å(30 °C)。[6]
性质及用途
四甲基碘化铵和叠氮化亚铊反应,可以得到四甲基叠氮化铵:[7]
- [(CH3)4N]I + TlN3 → [(CH3)4N]N3 + TlI
它与硫、氰化亚铜反应,可以得到配合物[(CH3)4N][Cu(SCN)I]。[8]它和碘化铅在γ-丁内酯中反应,可以得到具有钙钛矿结构的[(CH3)4N][PbI3]。[9]
它和路易斯酸共同使用,可用作四羰基钴钠催化的三甲胺羰基化反应的引发剂。[10]
