5-Substituted tetrazoles were prepared by treatment of nitriles with sodium azide and triethylammonium chloride in nitrobenzene in a microwave reactor. This practical method combines the advantages of previous procedures, including good-to-excellent yields, short reaction times, and easy isolation of the product. Moreover, sterically hindered tetrazoles, as well as those deactivated by electron-donating
通过在微波反应器中在硝基苯中用叠氮化钠和氯化三乙铵处理腈来制备5位取代的四唑。这种实用的方法结合了先前程序的优点,包括良率至优异的产量,较短的反应时间以及易于分离的产物。此外,可以制备位阻四唑以及被供电子基团钝化的四唑。 四唑-微波辐射-叠氮化钠-杂环-腈
