Alkylation of 5-aryltetrazoles with N-arylchloroacetamides commonly proceeds regioselectively at 2 position of the tetrazole ring. The ratio of 1,5- and 2,5-regioisomers depends on the nature of a substituents in the benzene ring of the N-arylchloroacetamide and position of a substituent in the aryltetrazole aryl group. Features of 1H NMR spectra of the synthesized compounds are discussed.
5-芳基四唑与N-芳基氯乙酰胺的烷基化通常在四唑环的2位区域选择性地进行。1,5-和2,5-区域异构体的比例取决于N-芳基氯乙酰胺的苯环中取代基的性质和芳基四唑芳基中取代基的位置。讨论了合成化合物的1 H NMR光谱特征。
