  摘要：

  式中R为芳基基团，例如苯基、萘基或联苯基，或是被一个或多个三氟甲基、溴或氰基取代的苯基；E1和E2分别为氢、烷基、芳基烷基等，通过在过渡金属催化剂（如醋酸钯(II)）存在下，将一种在苯环的5位被卤原子取代的苯并三氮唑与芳基硼酸或酯反应制备而成。式I的苯并三氮唑化合物特别适用于汽车涂料和蜡烛蜡的稳定剂。

  Compounds of formula I or II 1 where R is an aryl moiety, such as phenyl, naphthyl or biphenylyl, or is phenyl substituted by one or more trifluoromethyl, bromo or cyano, and E 1 and E 2 are independently hydrogen, alkyl, aralkyl and the like are prepared by reaction of a benzotriazole substituted on the 5-position of the benzo ring by a halogen atom with a arylboronic acid or ester in the presence of a transition-metal catalyst, such as palladium (II) diacetate. The benzotriazole compounds of formula I are particularly efficacious as stabilizers for automotive coatings and candle wax.

  公式I或II的化合物，其中R是芳基基团，例如苯基、萘基或联苯基，或是被一个或多个三氟甲基、溴或氰基替代的苯基；E1和E2独立地为氢、烷基、芳基烷基等。这些化合物是通过将5-位置被卤素原子取代的苯并三氮唑与芳基硼酸或酯在过渡金属催化剂（如二乙酸钯（II））的存在下反应制备而成。公式I的苯并三氮唑化合物特别适用于汽车涂料和蜡烛蜡的稳定剂。
