Synthesis of biaryls involving arylbismuth and arylantimony reagents 

Unfortunately, the method works well only with para- and /neto-substituted triarylbismuth compounds, while the /jara-substituted ones failed to give the reaction or resulted in very low yields [73]. Arylation of phenols and other electron-rich aromatics, e.g. indole, with triarylbismuth(V) dichlorides, carbonates and related compounds is readily affected under neutral conditions, by simple stirring in
