実験手順

Anhydrous ferric chloride (6.44 g, 0.038 mol) was added over a period of 30 minutes to a methylene chloride (300 ml) solution of 2-(2H-benzotriazol-2-yl)-4-tert-butyl-phenol (5.3 g, 0.019 mol) known as TINUVIN® PS Light Stabilizer, a product of CIBA SPECIALTIES, Hawthorne, N.Y. The resulting mixture was stirred at room temperature for 6 hours. After filtering over diatomaceous earth, the filtrate was extracted with dilute hydrochloric acid, washed with water and dried. Evaporation of the solvent gave 3,3′bis-(2H-benzotriazol-2-yl)-5,5′-di-tert-butyl-1,1′-biphenyl-2,2′-diol (COMPOUND 2) as a white powder; m.p. 234° C.
