Appl. No.:

09/722973

Inventors:

Stephen D. Pastor - Danbury CT

Ramanathan Ravichandran - Suffern NY

Assignee:

Ciba Specialty Chemicals Corporation - Tarrytown NY

International Classification:

C08K 53472

US Classification:

524 84, 524 91, 546 13, 546162, 546164, 5462684, 548110, 548259, 548260, 548261

Abstract:

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 E and E 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 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.

US Classification:

548260, 548113, 548261

Abstract:

2H-Benzotriazole UV absorbers substituted at the 3-position or at the 5-position of the phenyl ring by a 1,1-diphenylalkyl moiety, particularly a 1,1-diphenylethyl group, are particularly photostable in automotive coatings, and are of low color and exhibit low volatility in thermoplastic compositions.

International Classification:

C07D24920

US Classification:

548260

Abstract:

Compounds of formula I or II 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 and E 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.
