1- Chlorobenzotriazole stability

A major use for 2,4-di-/ f2 -amylphenol is in the production of uv stabilizers the principal one is a benzotriazole-based uv absorber, 2-(2 -hydroxy-3, 5 -di-/ f2 -amylphenyl)-5-chlorobenzotriazole [25973-55-17, which is widely used in polyolefin films, outdoor furniture, and clear coat automotive finishes (56). Another significant use for 2,4-di-/ f2 -amylphenol is in the photographic iadustry. A number of phenoxyacetic acid derivatives of... 

Most synthetic applications of benzotriazoles are based on the acceptor action of the benzotria-zol-l-yl moiety i.e. on the stability of the benzotriazolyl anion. For instance 1-chlorobenzotriazole is used as a chlorinating agent. It transfers a Cl ion to the substrate. An example of this reaction is the chlorination of carbazole in dichloromethane to give 3-chlorocarbazole. 1-Hydroxybenzotriazole is obtained by condensation of l-chloro-2-nitrobenzene with hydrazine ... 

Equimolar amounts of cyclohexanol and 1-chlorobenzotriazole warmed in methylene chloride until an exothermic reaction starts cyclohexanone. Y 70%. -The above new oxidant, a positive-chlorine compound, is potentially useful because of its easy prepn., stability, reactivity under mild conditions, and easy isolation of the products.
