  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.

  化合物的公式I或II1，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，溴或氰取代的苯基，E1和E2独立地是氢，烷基，芳基烷基等，通过苯并三唑在苯环的5位被卤素原子取代，与芳基硼酸或酯在过渡金属催化剂的存在下，例如二乙酸钯（II）反应制备而成。公式I的苯并三唑化合物特别适用于汽车涂料和蜡烛蜡的稳定剂。

  Hindered amines substituted on the N-atom with an —O—E—OH moiety are particularly effective in stabilizing polyolefin and automotive coating compositions against the deleterious effects of oxidative, thermal and actinic radiation where the presence of the OH group on the compounds adds important properties not attainable by the use of normal —O—E moieties.

  在N原子上取代了一个—O—E—OH基团的阻碍胺对稳定聚烯烃和汽车涂料组合物，以对抗氧化、热和光辐射的有害影响特别有效，其中化合物上OH基团的存在增加了重要性质，这是正常的—O—E基团所无法达到的。
