US Patent:

6387992, May 14, 2002

Filed:

Nov 27, 2000

Appl. No.:

09/722973

Inventors:

Stephen D. Pastor - Danbury CT

Mervin G. Wood - Poughquag NY
Joseph Suhadolnik - Yorktown Heights NY
Deborah DeHessa - Poughkeepsie NY
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.

Assignee:

Ciba Specialty Chemicals Corporation - Tarrytown NY

International Classification:

C08K 53475

US Classification:

524 89, 524 91, 524 94

Abstract:

Benzotriazole UV absorbers which are substituted at the 5-position of the benzo ring by an electron withdrawing group exhibit enhanced durability and very low loss rates when incorporated into automotive coatings. This is particularly the case when the 3-position of the phenyl ring is also substituted by phenyl or phenylalkyl such as -cumyl. Compounds where the 5-position of the benzo ring are substituted by perfluoroalkyl such as trifluoromethyl are particularly of interest for both their enhanced durability and for their excellent solubility and excellent color properties in some thermoplastic compositions when the phenyl ring is substituted at the 3-position by hydrogen or tert-alkyl.

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. The benzotriazole compounds of formula I are particularly efficacious as stabilizers for automotive coatings and candle wax.
