Copper(II)-catalyzed O-Phenylation of Alcohols with Organobismuth(V) Reagents: A Convenient Method for the Synthesis of Simple<i>tert</i>-Alkyl Phenyl Ethers
A convenient method for copper(II)-catalyzed O-phenylation of simple alcohols with organobismuth(V) compounds under mild conditions is described. Treatment of tetraphenylbismuth fluoride (Ph 4 BiF) with various simple alcohols in the presence of a catalytic amount of Cu II acetate affords the corresponding phenyl ethers in good yields and the present reaction is successfully applied to the prepararion

Metal-Free Etherification of Aryl Methyl Ether Derivatives by C–OMe Bond Cleavage
A general and efficient protocol was developed for the synthesis of aryl alkyl ethers through metal-free C–OMe bond cleavage under mild reaction conditions. This process displays a wide scope of methoxyarenes and alcohols, including primary, secondary, and tertiary alcohols, as well as natural products, pharmaceuticals, and biologically active alcohols.
