The synthesis of a new fluorous tin azide, (C6F13CH2CH2)3SnN3, is reported and this reagent is used to make tetrazoles in both traditional and phase-switching modes. In the traditional mode, the tin azide is reacted with nitriles followed by HCl cleavage to provide the tetrazoles and the fluorous tin chloride (which can be reconverted into the tin azide). In the switching mode, the initial tin tetrazole
据报道,合成了一种新型的氟叠氮化锡(C 6 F 13 CH 2 CH 2)3 SnN 3,该试剂可用于在传统和相转换模式下制备四唑。在传统模式下,叠氮化锡与腈反应,然后进行HCl裂解,得到四唑和氟代氯化锡(可以转化为叠氮化锡)。在切换模式下,在脱甲锡之前,先通过氟/有机液-液萃取法纯化初始的四唑锡。即使反应不完全或原料不纯,也能提供纯净的产品,但仅适用于较小的腈。

antibacterial properties of certain tetrazole derivatives have been described. We have previously reported the antibacterial properties of aryl 1Htetrazole compounds. Objective: To study the antibacterial activity of 5-substituted heteroaryl, vinyl, benzyl, and alkyl 1H-tetrazole derivatives. Methods: The antibacterial properties of heteroaryl, vinyl, benzylic, and aliphatic tetrazole derivatives were investigated

Condensation reactions of o-hydroxy- and o-mercaptoanilines, and o-phenylenediamine with (benzotriazol-1-yl)acetic acid result in (1,3-benzazol-2-yl)(benzotriazol-1-yl)methanes. Cycloaddition of sodium azide to (benzotriazol-1-yl)acetonitrile leads to (1,2,3,4-tetrazol-5-yl)(benzotriazol-1-yl)methane. The diazolo-substituted benzotriazolylmethanes thus obtained were mono- and di-alkylated at the methylene
