Copper(II)-Catalyzed O-Arylation of Tertiary Alcohols with Arylbismuth(III) Reagents: A Convenient System for Aryl Transfer

[摘要]：Copper(II)-catalyzed O-arylation of tertiary alcohols with various triarylbismuth reagents was investigated. A convenient and efficient system for aryl ether formation of tertiary alcohols has been developed through the in situ oxidation of stable triarylbismuth(III) to triarylbismuth(V) species using PhI(OAc)(2) as the oxidant in the presence of a catalytic amount of copper(II) acetate.
