A convenient method for Morita-Baylis-Hillman reaction of arylaldehydes with methyl acrylate has been developed by using fluorous-tag organocatalyst 1-[4-(perfluorooctyl)phenyl]-3-phenylthiourea and DABCO at room temperature. The fluorous organocatalyst could be recovered from the reaction mixture by fluorous solid-phase extraction (F-SPE) with excellent purity for direct reuse.
以甲胺和叠氮化氰为原料经缩合作用合成了1-甲基-5-氨基四唑,在发烟硝酸最佳用量为5mL、室温和反应时间20h条件下,经硝化得到1-甲基-5-硝亚胺基四唑。通过1-甲基-5-硝亚胺基四唑作阴离子和5种高氮含能阳离子的反应,分别合成出1-甲基-5-硝亚胺基四唑铵盐、1-甲基-5-硝亚胺基四唑肼盐、1-甲基-5-硝亚胺基四唑胍盐、1-甲基-5-硝亚胺基四唑5-氨基四唑盐、1-甲基-5-硝亚胺基四唑3,6-二肼基四嗪盐5种盐的含能化合物。用红外、1 H NMR、13 C NMR及元素分析对产物进行了表征。
