Beschreibung
Zusammenfassung:	Compounds of formula (I) or (II) where R is a heteroaryl moiety, such as 3-pyridyl; or R is an aryl moiety, such as phenyl, naphthyl or biphenylyl, or is phenyl substituted by one or more trifluoromethyl, bromo or cyano; T is a heteroaryl moiety, such as thien-2,5-diyl or is a direct bond, 1,4-phenylene or said phenylenen substituted by one or two alkyl of 1 to 12 carbon atoms, and E1 and E2 are independently hydrogen, alkyl, aralkyl and the like, are prepared by reaction of a benzotriazole substituted on the 5-position of the benzo zing by a halogen atom with a heteroarylboronic acid or ester in the presence of a transition-metal catalyst, such as palladium (II) diacetate. The benzotriarole compounds of formula (I) or (II) are particularly efficacious as stabilizers for automotive coatings and candle wax.
