A mild and efficient protocol for O-arylation of alcohols and phenols (ROH) by triarylsulfonium triflates was developed under transition-metal-free conditions. Various alcohols, including primary, secondary and tertiary, and phenols bearing either electron-donating or electron-withdrawing groups on the aryl rings were smoothly converted to form the corresponding aromatic ethers in moderate to excellent

The Ph3P/ICH2CH2I system-promoted dehydroxylative substitution of alcohols was achieved to construct C–O, C–N, C–S and C–X (X = Cl, Br, and I) bonds. Compared with the previous approaches such as the Appel reaction and Mitsunobu reaction, this protocol offers some practical advantages such as safe operation and a convenient amination process.

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
