Ethylaryl- and diethylaryl(benzotriazol-1-yl)methanes, obtained by mono- or dialkylation of substituted (benzotriazol-1-ylmethyl)benzenes, react with sodium alkoxides, phenol and thiophenol to yield the corresponding α-di- and α-trisubstituted ethers and sulfides. With amines, instead of nucleophile displacement, products arising from reduction or elimination are formed.
乙基芳基和二乙基芳基(苯并三唑-1-基)甲烷是通过取代(苯并三唑-1-基甲基)苯的单烷基或二烷基化反应得到的,它们与烷氧基化钠、苯酚和噻吩酚反应生成相应的δ-二和δ-三取代醚和硫化物。与胺反应时,生成的不是亲核置换,而是还原或消除产物。
