Abstract
A convenient method for the Cu(II)-catalyzed O-phenylation of tertiary alcohols with organobismuth(V) compounds under mild conditions is described. Functionalized tertiary alcohols such as α-hydroxy carbonyl compounds were phenylated by using either Ph3Bi(OAc)2 or tetraphenylbismuth compounds. In the cases of O-phenylation of simple tertiary alcohols, the use of tetraphenylbismuth fluoride (Ph4BiF) was particularly effective and gave various tert- alkyl phenyl ethers in high yields. The synthesis of alkyl phenyl ethers from primary and secondary alcohols are also described.
