| 摘 要： | 以氯化二乙基铝（ＤＥＣＡ）和叠氮化钠为原料合成二乙基叠氮铝（ＤＥＡＡ）时，反应介质的溶剂性质不同，产物及其收率也不同。在给电子溶剂四氢呋喃（ＴＨＦ）或烃与ＴＨＦ混合溶剂中，反应产物是ＤＥＡＡ·ＴＨＦ络合物；在给电子能力较弱的烃类溶剂中，得到ＤＥＡＡ，且以三聚体形式存在；在无给电子能力的烃类溶剂中如正己烷、环己烷中，没有得到任何反应产物。随着溶剂给电子能力增加，依次用正己烷、环己烷、苯、甲苯、二甲苯、三甲苯为反应介质时，ＤＥＡＡ的收率由零逐渐增大。此外，还讨论了溶剂在合成ＤＥＡＡ反应中的其它化学作用

| Abstract: | The solvent effect on the synthesis of diethylaluminum azide(DEAA)
from diethylaluminum chloride(DECA) and sodium azide(NaN3) is discussed.In electrondonor
tetrahydrofuran(THF) or its mixture with hydrocarbon as the reaction medium the product is
DEAATHF complex; in weak electrondonor like hydrocarbon the reaction product is DEAA which
exists as trime; when nonelectrondonor agent like hexane or cyclohexane is used as the
reaction solvent,there is no product formed.With increase of electrondonation of the solvent the
product yield also increases,for example, the yield of DEAA sequentially increases in the
reaction medium of benzene,tuluene,dimethyl and trimethylbenzene.The other chemical effect
of solvents on the reaction of NaN3 and DECA is also discussed. |
