Abstract:
Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstituted benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.

Claim (Index 20):
A method of preparing a substituted benzotriazole phenol comprising:\n providing a protected phenolic compound of Formula III: wherein the group P is a protective group comprising an alkyl, a substituted alkyl, or a silyl group; R 1  comprises a leaving group selected from a halogen atom, a triflate group, a tosylate group, or a sulfonate group; and each R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 , independently comprises a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, or a halogen atom; providing a compound with the general formula R 21 \u2014Z\u2014X\u2014H\n wherein R 21  comprises a hydrogen atom, an alkyl group, an alkenyl group, an \n aryl group, or a halogen atom; \n Z comprises an alkyl or aryl group, or a single bond; \n X comprises an \u2014O\u2014, \u2014NR 10 \u2014, \u2014S(O)\u2014, or \u2014S\u2014 linking group where R 10  comprises \n a hydrogen atom, an alkyl group, or an aryl group; \n providing a palladium-based catalyst comprising at least one palladium-phosphine complex; providing at least one base; providing at least one solvent; mixing the protected phenolic compound of Formula III, the compound with the general formula R 21 \u2014Z\u2014X\u2014H, the palladium-based catalyst, the at least one base, and the at least one solvent to form a reaction mixture; and heating the reaction mixture to a temperature of at least 100\u00b0 C. to effect a coupling reaction.
