COUMESTAN-LIKE ANTIOXIDANTS AND UV ABSORBANTS

The present invention relates to derivatives of the 1H-pyrano[4,3-b]benzofuran-1-one structure and their nitrogen analogues which possess powerful antioxidant properties combined with a highly effective UV absorbing functionality in one molecule. These compounds are especially useful in cosmetical and dermatological formulations.

Substituted 5-heteroaryl-2-(2-hydroxyphenyl)-2h-benzotriazole UV absorbers, a process for preparation thereof and compositions stabilized therewith

Compounds of formula I or II where R is a heteroaryl moiety, such as 3-pyridyl, or T is a heteroaryl moiety, such as thien-2,5-diyl, and E1and E2are 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 heteroarylboronic 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.
