Preparation of 2-aryl-2H-benzotriazoles by zinc-mediated reductive cyclization of o-nitrophenylazophenols in aqueous media without the use of organic solvents

Zinc powder-mediated reductive cyclization of o-nitrophenylazophenols in alkaline solution affords the corresponding 2-aryl-2H-benzotriazoles in high yields under mild reaction conditions. No organic solvents are used in the reaction and only minimal amounts in the work-up.

High molecular weight piperidine derivatives as UV stabilizers

Substituted high molecular weight hindered spiropiperidine compounds and polymer compositions stabilized by these compounds. The spiropiperidine compounds are prepared by reacting hindered 4-piperidinone hydrochloride with an activated benzene, such as resorcinol, in an acid medium.
