Arylbismuth compounds are effective reagents for the O-arylation of alcohols, phenols, and other oxygen nucleophiles. Depending on the reaction conditions, carbonyl compounds and phenols can be C-arylated (see Section or O-arylated. The O-arylation of 5,5-dimethylcyclohexane-1,3-dione was accomplished using bis(trifluoroacetoxy)triphenylbismuth(V) in the presence of 10 mol% metallic copper[‌314‌] or (trifluoroacetoxy)tetraphenylbismuth(V) in the presence of 0.6 equivalents of trichloroacetic acid.[‌311‌] The O-arylation of ethyl 2-oxocyclohexane-1-carboxylate using (trifluoroacetoxy)tetraphenylbismuth(V) has been realized, but trichloroacetic acid had to be replaced by 2-tert-butyl-1,1,3,3-tetramethylguanidine for optimal yields.[‌311‌]
